Subject: drm/msm/dpu: enable DPU_CTL_SPLIT_DISPLAY for sc8280xp

Theoretically, since sm8150 we should be using a single CTL for the
split panel case, but since we do not support it for now, fallback to
DPU_CTL_SPLIT_DISPLAY.

Subject: drm/msm/dpu: use CTL_SC7280_MASK for sm8450's ctl_0

On sm8450 platform the CTL_0 doesn't differ from the rest of CTL blocks,
so switch it to CTL_SC7280_MASK too.

Some background: original commit 100d7ef6995d ("drm/msm/dpu: add support
for SM8450") had all (relevant at that time) bit spelled individually.
Then commit 0e91bcbb0016 ("drm/msm/dpu: Add SM8350 to hw catalog"),
despite being a mismerge, correctly changed all other CTL entries to use
CTL_SC7280_MASK, except CTL_0.

While the current BLOCK_SOC_MASK style is not ideal (and while we are
working on a better scheme), let's follow its usage as a least minimal
surprise. For example, sc8280xp, a close associate of sm8450, also uses
CTL_SC7280_MASK.

Subject: drm/msm/dpu: simplify intf allocation code

Rather than passing DRM_MODE_ENCODER_* and letting dpu_encoder to guess,
which intf type we mean, pass INTF_DSI/INTF_DP directly. This is
required to support HDMI output in DPU, as both DP and HDMI encoders are
DRM_MODE_ENCODER_TMDS. Thus dpu_encoder code can not make a difference
between HDMI and DP outputs.

Subject: drm/msm/dsi: Stop unconditionally powering up DSI hosts at modeset

In commit 7d8e9a90509f ("drm/msm/dsi: move DSI host powerup to modeset
time"), we moved powering up DSI hosts to modeset time. This wasn't
because it was an elegant design, but there were no better options.

That commit actually ended up breaking ps8640, and thus was born
commit ec7981e6c614 ("drm/msm/dsi: don't powerup at modeset time for
parade-ps8640") as a temporary hack to un-break ps8640 by moving it to
the old way of doing things. It turns out that ps8640 _really_ doesn't
like its pre_enable() function to be called after
dsi_mgr_bridge_power_on(). Specifically (from experimentation, not
because I have any inside knowledge), it looks like the assertion of
"RST#" in the ps8640 runtime resume handler seems like it's not
allowed to happen after dsi_mgr_bridge_power_on()

Recently, Dave Stevenson's series landed allowing bridges some control
over pre_enable ordering. The meaty commit for our purposes is
commit 4fb912e5e190 ("drm/bridge: Introduce pre_enable_prev_first to
alter bridge init order"). As documented by that series, if a bridge
doesn't set "pre_enable_prev_first" then we should use the old ordering.

Now that we have the commit ("drm/bridge: tc358762: Set
pre_enable_prev_first") we can go back to the old ordering, which also
allows us to remove the ps8640 special case.

One last note is that even without reverting commit 7d8e9a90509f
("drm/msm/dsi: move DSI host powerup to modeset time"), if you _just_
revert the ps8640 special case and try it out then it doesn't seem to
fail anymore. I spent time bisecting / debugging this and it turns out
to be mostly luck, so we still want this patch to make sure it's
solid. Specifically the reason it sorta works these days is because
we implemented wait_hpd_asserted() in ps8640 now, plus the magic of
"pm_runtime" autosuspend. The fact that we have wait_hpd_asserted()
implemented means that we actually power the bridge chip up just a wee
bit earlier and then the bridge happens to stay on because of
autosuspend and thus ends up powered before dsi_mgr_bridge_power_on().

Subject: drm/msm/dsi: More properly handle errors in regards to
 dsi_mgr_bridge_power_on()

In commit 7d8e9a90509f ("drm/msm/dsi: move DSI host powerup to modeset
time") the error handling with regards to dsi_mgr_bridge_power_on()
got a bit worse. Specifically if we failed to power the bridge on then
nothing would really notice. The modeset function couldn't return an
error and thus we'd blindly go forward and try to do the pre-enable.

In commit ec7981e6c614 ("drm/msm/dsi: don't powerup at modeset time
for parade-ps8640") we added a special case to move the powerup back
to pre-enable time for ps8640. When we did that, we didn't try to
recover the old/better error handling just for ps8640.

In the patch ("drm/msm/dsi: Stop unconditionally powering up DSI hosts
at modeset") we've now moved the powering up back to exclusively being
during pre-enable. That means we can add the better error handling
back in, so let's do it. To do so we'll add a new function
dsi_mgr_bridge_power_off() that's matches how errors were handled
prior to commit 7d8e9a90509f ("drm/msm/dsi: move DSI host powerup to
modeset time").

NOTE: Now that we have dsi_mgr_bridge_power_off(), it feels as if we
should be calling it in dsi_mgr_bridge_post_disable(). That would make
some sense, but doing so would change the current behavior and thus
should be a separate patch. Specifically:
* dsi_mgr_bridge_post_disable() always calls dsi_mgr_phy_disable()
  even in the slave-DSI case of bonded DSI. We'd need to add special
  handling for this if it's truly needed.
* dsi_mgr_bridge_post_disable() calls msm_dsi_phy_pll_save_state()
  midway through the poweroff.
* dsi_mgr_bridge_post_disable() has a different order of some of the
  poweroffs / IRQ disables.
For now we'll leave dsi_mgr_bridge_post_disable() alone.

Subject: drm/msm/dsi: don't allow enabling 14nm VCO with unprogrammed rate

If the dispcc uses CLK_OPS_PARENT_ENABLE (e.g. on QCM2290), CCF can try
enabling VCO before the rate has been programmed. This can cause clock
lockups and/or other boot issues. Program the VCO to the minimal PLL
rate if the read rate is 0 Hz.

Subject: drm/msm/dpu: use hsync/vsync polarity set by the encoder

Do not override the hsync/vsync polarity passed by the encoder when
setting up intf timings. The same logic was used in both the encoder and
intf code to set the DP and DSI polarities, so those interfaces are not
impacted. However for HDMI, the polarities were overriden to static
values based on the vertical resolution, instead of using the actual
mode polarities.

Subject: drm/msm/dpu: set max cursor width to 512x512

Override the default max cursor size reported to userspace of 64x64.
MSM8998 hw cursor planes support 512x512 size, and other chips use DMA
SSPPs.

Subject: drm/msm/dpu: drop the regdma configuration

The regdma is currently not used by the current driver. We have no way
to practically verify that the regdma is described correctly. Drop it
now.

Subject: drm/msm/dpu: Drop unused members from HW structs

Some of these members were initialized while never read, while others
were not even assigned any pointer value at all.  Drop them to save some
space, and above all confusion when looking at or accidentally
dereferencing these members.

Subject: drm/msm/dpu: Pass catalog pointers in RM to replace for-loop ID
 lookups

The Resource Manager already iterates over all available blocks from the
catalog, only to pass their ID to a dpu_hw_xxx_init() function which
uses an _xxx_offset() helper to search for and find the exact same
catalog pointer again to initialize the block with, fallible error
handling and all.

Instead, pass const pointers to the catalog entries directly to these
_init functions and drop the for loops entirely, saving on both
readability complexity and unnecessary cycles at boot.

Subject: drm/msm/dpu: remove DPU_DSPP_GC handling in dspp flush

Gamma correction blocks (GC) are not used today so lets remove
the usage of DPU_DSPP_GC in the dspp flush to make it easier
to remove GC from the catalog.

We can add this back when GC is properly supported in DPU with
one of the standard DRM properties.

changes in v3:
	- drop the link tag which was auto added before

Subject: drm/msm/dpu: remove GC and IGC related code from dpu catalog

Gamma Correction (GC) and Inverse Gamma Correction(IGC) is
currently unused. In addition dpu_dspp_sub_blks didn't even have an igc
member describing the block.

Drop related code from the dpu hardware catalog otherwise this becomes a
burden to carry across chipsets in the catalog.

changes in v3:
	- drop IGC related code from dpu_hw_catalog too
	- update commit text accordingly

Subject: drm/msm/dpu: drop DSPP_MSM8998_MASK from hw catalog

Since GC and IGC masks have now been dropped, DSPP_MSM8998_MASK
is the same as DSPP_SC7180_MASK. Since DSPP_SC7180_MASK is used more
than DSPP_MSM8998_MASK, lets drop the latter.

Subject: drm/msm/dpu: Use V4.0 PCC DSPP sub-block in SC7[12]80

According to various downstream sources the PCC sub-block inside DSPP is
version 4.0 since DPU 4.0 and higher, including SC7[12]80 at DPU version
6.2 and 7.2 respectively.  After correcting the version this struct
becomes identical to sm8150_dspp_sblk which is used all across the
catalog: replace uses of sc7180_dspp_sblk with that and remove
the struct definition for sc7180_dspp_sblk entirely.

Subject: drm/msm/dpu: Remove extraneous register define indentation

A bunch of registers are indented with two extra spaces, looking as if
these are values corresponding to the previous register which is not the
case, rather these are simply also register offsets and should only have
a single space separating them and the #define keyword.

A bunch of registers were appended at the end in e.g. commit

rather than being inserted in a place that maintains numerical sorting:
restore said numerical sorting.

Subject: drm/msm/dpu: Take INTF index as parameter in interrupt register
 defines

Instead of hardcoding many register defines for every INTF and AD4 index
with a fixed stride, turn the defines into singular chunks of math that
compute the address using the base and this fixed stride multiplied by
the index given as argument to the definitions.

MDP_SSPP_TOP0_OFF is dropped as that constant is zero anyway, and all
register offsets related to it live in dpu_hwio.h.

Subject: drm/msm/dpu: Drop unused poll_timeout_wr_ptr PINGPONG callback

This callback was migrated from downstream when DPU1 was first
introduced to mainline, but never used by any component.  Drop it to
save some lines and unnecessary confusion.

From: Marijn Suijten

Subject: drm/msm/dpu: Move autorefresh disable from CMD encoder to pingpong

This autorefresh disable logic in the physical command-mode encoder
consumes three callbacks to the pingpong block, and will explode in
unnecessary complexity when the same callbacks need to be called on the
interface block instead to accommodate INTF TE support.  To clean this
up, move the logic into the pingpong block under a disable_autorefresh
callback, replacing the aforementioned three get_autorefresh,
setup_autorefresh and get_vsync_info callbacks.

The same logic will have to be replicated to the interface block when it
receives INTF TE support, but it is less complex than constantly
switching on a "has_intf_te" boolean to choose a callback.

From fe9d66cf6e8d2f6651e55ae57026464a080c2f2a Mon Sep 17 00:00:00 2001
From: Marijn Suijten

Subject: drm/msm/dpu: Disable pingpong TE on DPU 5.0.0 and above

Since hardware revision 5.0.0 the TE configuration moved out of the
PINGPONG block into the INTF block.  Writing these registers has no
effect, and is omitted downstream via the DPU/SDE_PINGPONG_TE feature
flag.  This flag is only added to PINGPONG blocks used by hardware prior
to 5.0.0.

The existing PP_BLK_TE macro has been removed in favour of directly
passing this feature flag, which has thus far been the only difference
with PP_BLK.  PP_BLK_DITHER has been left in place as its embedded
feature flag already excludes this DPU_PINGPONG_TE bit and differs by
setting the block length to zero, as it only contains a DITHER subblock.

The code that writes to these registers in the INTF block will follow in
subsequent patches.

Subject: drm/msm/dpu: Disable MDP vsync source selection on DPU 5.0.0 and
 above

Since hardware revision 5.0.0 the TE configuration moved out of the
PINGPONG block into the INTF block, including vsync source selection
that was previously part of MDP top.  Writing to the MDP_VSYNC_SEL
register has no effect anymore and is omitted downstream via the
DPU/SDE_MDP_VSYNC_SEL feature flag.  This flag is only added to INTF
blocks used by hardware prior to 5.0.0.

The code that writes to these registers in the INTF block will follow in
subsequent patches.

Now that newer SoCs since DPU 5.0.0 manage tearcheck in the INTF instead
of PINGPONG block, move the struct definition to a common file. Also,
bring in documentation from msm-4.19 techpack while at it.

Subject: drm/msm/dpu: Factor out shared interrupt register in INTF_BLK macro

As the INTF block is going to attain more interrupts that don't share
the same MDP_SSPP_TOP0_INTR register, factor out the _reg argument for
the caller to construct the right interrupt index (register and bit
index) to not make the interrupt bit arguments depend on one of multiple
interrupt register indices.  This brings us more in line with how PP_BLK
specifies its interrupts and allows for better wrapping in the arrays.

Subject: drm/msm/dpu: Describe TEAR interrupt registers for DSI interfaces

All SoCs since DPU 5.0.0 have the tear interrupt registers moved out of
the PINGPONG block and into the INTF block.  Wire up the IRQ register
masks in the interrupt table for enabling, reading and clearing them.

Subject: drm/msm/dpu: Add TEAR-READ-pointer interrupt to INTF block

All SoCs since DPU 5.0.0 have the tear interrupt registers moved out of
the PINGPONG block and into the INTF block.  The new interrupts are
described in dpu_hw_interrupts.c, now wire them up in individual SoC
catalog files by setting the intr_tear_rd_ptr to the IRQ index spcified
in the offset table and enabling this set of DPU interrupts via the

Subject: drm/msm/dpu: Merge setup_- and enable_tearcheck pingpong callbacks

These functions are always called consecutively and are best bundled
together for simplicity, especially when the same structure of callbacks
will be replicated later on the interface block for INTF TE support.
The enable_tearcheck(false) case is now replaced with a more obvious
disable_tearcheck(), encapsulating the original register write with 0.

Subject: drm/msm/dpu: Implement tearcheck support on INTF block

Since DPU 5.0.0 the TEARCHECK registers and interrupts moved out of the
PINGPONG block and into the INTF.  Implement the necessary callbacks in
the INTF block, and use these callbacks together with the INTF_TEAR
interrupts.

Subject: drm/msm/dpu: Remove intr_rdptr from DPU >= 5.0.0 pingpong config

Now that newer DPU platforms use a readpointer-done interrupt on the
INTF block, stop providing the unused interrupt on the PINGPONG block.

Subject: drm/msm/dpu: drop SSPP's SRC subblock

The src_blk declares a lame copy of main SSPP register space. It's
offset is always 0. It's length has been fixed to 0x150, while SSPP's
length is now correct. Drop the src_blk and access SSPP registers
without additional subblock lookup.

Subject: drm/msm/dpu: replace IS_ERR_OR_NULL with IS_ERR during DSC init

Using IS_ERR_OR_NULL() together with PTR_ERR() is a typical mistake. If
the value is NULL, then the function will return 0 instead of a proper
return code. Moreover dpu_hw_dsc_init() can not return NULL.
Replace the IS_ERR_OR_NULL() call with IS_ERR().

This follows the commit 740828c73a36 ("drm/msm/dpu: fix error handling
in dpu_rm_init"), which removed IS_ERR_OR_NULL() from RM init code, but
then the commit f2803ee91a41 ("drm/msm/disp/dpu1: Add DSC support in
RM") added it for DSC init.

Subject: drm/msm/dpu: remove futile checks from dpu_rm_init()

dpu_rm_init() contains checks for block->id values. These were logical
in the vendor driver, when one can not be sure which values were passed
from DT. In the upstream driver this is not necessary: the catalog is a
part of the driver, we control specified IDs.

Subject: drm/msm/dpu: use PINGPONG_NONE for LMs with no PP attached

On msm8998/sdm845 some LM blocks do not have corresponding PINGPONG
block. Currently the driver uses PINGPONG_MAX for such cases. Switch
that to use PINGPONG_NONE instead, which is more logical.

Subject: drm/msm/dpu: simplify CDP programming

Get rid of intermediatory configuration structure and defines. Pass the
format and the enablement bit directly to the new helper. The
WB_CDP_CNTL register ignores BIT(2), so we can write it for both SSPP
and WB CDP settings.

Subject: drm/msm/dpu: fix the condition for (not) applying QoS to CURSOR SSPP

The function dpu_plane_sspp_update_pipe() contains code to skip enabling
the QoS and OT limitis for CURSOR pipes. However all DPU since sdm845
repurpose DMA SSPP for the cursor planes because they lack the real
CURSOR SSPP. Fix the condition to actually check that the plane is
CURSOR or not.

After removal of DPU_PLANE_QOS_VBLANK_CTRL, several fields of struct
dpu_hw_pipe_qos_cfg are fixed to false/0. Drop them from the structure
(and drop the corresponding code from the functions).

The DPU_PLANE_QOS_VBLANK_AMORTIZE flag is also removed, since it is now
a NOP.

Subject: drm/msm/dsi: remove extra call to dsi_get_pclk_rate()

In dsi_calc_clk_rate_v2() there is no need to call dsi_get_pclk_rate().
This function has just been called (from dsi_calc_pclk()) and its
result is stored at msm_host->pixel_clk_rate. Use this variable
directly.

Simplify calculations around pixel_clk_rate division. Replace common
pattern of doing 64-bit multiplication and then a do_div() call with
simpler mult_frac() invocation.

Subject: drm/msm/dpu: set DSC flush bit correctly at MDP CTL flush register

The CTL_FLUSH register should be programmed with the 22th bit
(DSC_IDX) to flush the DSC hardware blocks, not the literal value of
22 (which corresponds to flushing VIG1, VIG2 and RGB1 instead).

Changes in V12:
-- split this patch out of "separate DSC flush update out of interface"

Changes in V13:
-- rewording the commit text

Changes in V14:
-- drop 'DSC" from "The DSC CTL_FLUSH register" at commit text

Subject: drm/msm/dpu: add DPU_PINGPONG_DSC feature bit for DPU < 7.0.0

DPU < 7.0.0 requires the PINGPONG block to be involved during
DSC setting up. Since DPU >= 7.0.0, enabling and starting the DSC
encoder engine was moved to INTF with the help of the flush mechanism.
Add a DPU_PINGPONG_DSC feature bit to restrict the availability of
dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() on the
PINGPONG block to DPU < 7.0.0 hardware, as the registers are not
available on DPU 7.0.0 and higher anymore.
Add DPU_PINGPONG_DSC to PINGPONG_SDM845_MASK, PINGPONG_SDM845_TE2_MASK
and PINGPONG_SM8150_MASK which is used for all DPU < 7.0 chipsets.

-- delete BIT(DPU_PINGPONG_DSC) from PINGPONG_SDM845_TE2_MASK

Subject: drm/msm/dpu: Guard PINGPONG DSC ops behind DPU_PINGPONG_DSC bit

DPU < 7.0.0 has DPU_PINGPONG_DSC feature bit set to indicate it requires
both dpu_hw_pp_setup_dsc() and dpu_hw_pp_dsc_{enable,disable}() to be
executed to complete DSC configuration if DSC hardware block is present.
Hence test DPU_PINGPONG_DSC feature bit and assign DSC related functions
to the ops of PINGPONG block accordingly if DPU_PINGPONG_DSC bit is set.

Changes in v6:
-- split patches, this patch has function handles DPU_PINGPONG_DSC bit

Changes in v9:
-- the original code of assigning dsc related functions to the ops of
   pingpong block without testing the DPU_PINGPONG_DSC feature bit was
   restored back due to rebase error which defeat the purpose of this
   patch. Remove those error code.

Changes in v10:
-- change commit title
-- correct texts at changes in v9

Changes in v12:
-- fixed length too long at Changes in v9

Subject: drm/msm/dpu: Introduce PINGPONG_NONE to disconnect DSC from PINGPONG

Disabling the crossbar mux between DSC and PINGPONG currently
requires a bogus enum dpu_pingpong value to be passed when calling
dsc_bind_pingpong_blk() with enable=false, even though the register
value written is independent of the current PINGPONG block.  Replace
that `bool enable` parameter with a new PINGPONG_NONE dpu_pingpong
flag that triggers the write of the "special" 0xF "crossbar
disabled" value to the register instead.

Changes in v4:
-- more details to commit text

Changes in v5:
-- rewording commit text suggested by Marijn
-- add DRM_DEBUG_KMS for DSC unbinding case

Changes in v8:

Subject: drm/msm/dpu: always clear every individual pending flush mask

There are two tiers of pending flush control, top level and
individual hardware block. Currently only the top level of
flush mask is reset to 0 but the individual pending flush masks
of particular hardware blocks are left at their previous values,
eventually accumulating all possible bit values and typically
flushing more than necessary.
Reset all individual hardware block flush masks to 0 to avoid
accidentally flushing them.

to handle both per-DSC engine and DSC flush bits at same time to make it
consistent with the location of flush programming of other DPU sub-blocks.

Changes in v10:
-- rewording commit text
-- pass ctl directly instead of dpu_enc to dsc_pipe_cfg()
-- ctx->pending_dsc_flush_mask = 0;

Changes in v11:
-- add Fixes tag

Changes in v12:
-- move dsc parameter to next line at dpu_encoder_dsc_pipe_cfg()

Changes in v14:
-- Fixes tag had been move to 1st patch of this series

Subject: drm/msm/dpu: Tear down DSC datapath on encoder cleanup

Unset DSC_ACTIVE bit at dpu_hw_ctl_reset_intf_cfg_v1(),
dpu_encoder_unprep_dsc() and dpu_encoder_dsc_pipe_clr() functions
to tear down DSC data path if DSC data path was setup previous.

Changes in V10:
-- pass ctl directly instead of dpu_enc to dsc_pipe_cfg()
-- move both dpu_encoder_unprep_dsc() and dpu_encoder_dsc_pipe_clr() to above phys_cleanup()

Subject: drm/msm/dpu: clean up dpu_kms_get_clk_rate() returns

Static analysis tools complain about the -EINVAL error code being
stored in an unsigned variable.  Let's change this to match
the clk_get_rate() function which is type unsigned long and returns
zero on error.

Subject: drm/msm/dsi: Add phy configuration for MSM8226

MSM8226 uses a modified PLL lock sequence compared to MSM8974, which is
based on the function dsi_pll_enable_seq_m in the msm-3.10 kernel.

Worth noting that the msm-3.10 downstream kernel also will try other
sequences in case this one doesn't work, but during testing it has shown
that the _m sequence succeeds first time also:

  .pll_enable_seqs[0] = dsi_pll_enable_seq_m,
  .pll_enable_seqs[1] = dsi_pll_enable_seq_m,
  .pll_enable_seqs[2] = dsi_pll_enable_seq_d,
  .pll_enable_seqs[3] = dsi_pll_enable_seq_d,
  .pll_enable_seqs[4] = dsi_pll_enable_seq_f1,
  .pll_enable_seqs[5] = dsi_pll_enable_seq_c,
  .pll_enable_seqs[6] = dsi_pll_enable_seq_e,

We may need to expand this in the future.

Subject: drm/msm/dpu: drop duplicated intf/wb indices from encoder structs

Remove intf_idx and wb_idx fields from struct dpu_encoder_phys and
struct dpu_enc_phys_init_params. Set the hw_intf and hw_wb directly and
use them to get the instance index.

Subject: drm/msm/dpu: inline dpu_encoder_get_wb()

The function dpu_encoder_get_wb() returns controller_id if the
corresponding WB is present in the catalog. We can inline this function
and rely on dpu_rm_get_wb() returning NULL for indices for which the
WB is not present on the device.

Subject: drm/msm/dpu: call dpu_rm_get_intf() from dpu_encoder_get_intf()

There is little sense to get intf index just to call dpu_rm_get_intf()
on it. Move dpu_rm_get_intf() call to dpu_encoder_get_intf() function.

Subject: drm/msm/dpu: simplify dpu_encoder_phys_wb_init()

There is no need to assign a result to temp varable just to return it
after a goto. Drop the temporary variable and goto and return the result
directly.

Subject: drm/msm/dp: remove most of usbpd-related remains

Remove most of remains of downstream usbpd code. Mainline kernel uses
different approach for managing Type-C / USB-PD, so this remains unused.

Subject: drm/msm/dp: Clean up logs dp_power module

The clk_bulk API already provides error messages indicating which
specific clock in the request for which the operation failed, further
more these errors are associated with the specific DisplayPort
controller (rather than the shared drm_device). The additional error
messages int he dp_power module does thereby not provide any benefit.

While at it, none of the dp_power handles passed to these functions are
dynamic in nature, so there should not be any need for runtime checking
them. Drop these as well.

Subject: drm/msm/dp: Clean up pdev/dev duplication in dp_power

The dp_power module keeps track of both the DP controller's struct
platform_device and struct device - with the prior pulled out of the
dp_parser module.

Clean up the duplication by dropping the platform_device reference and
just track the passed struct device.

Subject: drm/msm/dpu: use PINGPONG_NONE to unbind INTF from PP

Currently the driver passes the PINGPONG index to
dpu_hw_intf_ops::bind_pingpong_blk() callback and uses separate boolean
flag to tell whether INTF should be bound or unbound. Simplify this by
passing PINGPONG_NONE in case of unbinding and drop the flag completely.

Subject: drm/msm/dpu: Add SM6350 support

Add SM6350 support to the DPU1 driver to enable display output.

It's worth noting that one entry dpu_qos_lut_entry was trimmed off:

{.fl = 0, .lut = 0x0011223344556677 },

due to the lack of support for selecting between portrait and landscape
LUT settings (for danger and safe LUTs) and no full support for
qseed/non-qseed usescases (for QoS LUT).

Subject: drm/msm/dpu: tidy up some error checking

The "vsync_hz" variable is unsigned int so it can't be less
than zero.  The dpu_kms_get_clk_rate() function used to return a u64
but I previously changed it to return an unsigned long and zero on
error so it matches clk_get_rate().

Change the "vsync_hz" type to unsigned long as well and change the
error checking to check for zero instead of negatives.  This change
does not affect runtime at all.  It's just a clean up.

Subject: drm/msm/adreno: fix sparse warnings in a6xx code

Sparse reports plenty of warnings against the a6xx code because of
a6xx_gmu::mmio and a6xx_gmu::rscc members. For some reason they were
defined as __iomem pointers rather than pointers to __iomem memory.
Correct the __iomem attribute.

Subject: drm/msm/a5xx: really check for A510 in a5xx_gpu_init

The commit 010c8bbad2cb ("drm: msm: adreno: Disable preemption on Adreno
510") added special handling for a510 (this SKU doesn't seem to support
preemption, so the driver should clamp nr_rings to 1). However the
gpu->revn is not yet set (it is set later, in adreno_gpu_init()) and
thus the condition is always false. Check config->rev instead.

Subject: drm/msm/adreno: warn if chip revn is verified before being set

The commit 010c8bbad2cb ("drm: msm: adreno: Disable preemption on Adreno
510") tried to check GPU's revn before revn being set. Add WARN_ON_ONCE
to prevent such bugs from happening again. A separate helper is
necessary so that the warning is displayed really just once instead of
being displayed for each of comparisons.

Subject: drm/msm/adreno: make adreno_is_a690()'s argument const

Change adreno_is_a690() prototype to accept the const struct adreno_gpu
pointer instead of a non-const one. This fixes the following warning:

In file included from drivers/gpu/drm/msm/msm_drv.c:33:

Subject: drm/msm/dpu: do not enable color-management if DSPPs are not
 available

We can not support color management without DSPP blocks being provided
in the HW catalog. Do not enable color management for CRTCs if num_dspps
is 0.

Fixes: 4259ff7ae509 ("drm/msm/dpu: add support for pcc color block in dpu driver")

Subject: drm/msm/dpu: Use fixed DRM DSC helper for det_thresh_flatness

The current dpu_hw_dsc calculation for det_thresh_flatness does not
match the downstream calculation or the DSC spec.

Use the DRM DSC helper for det_thresh_flatness to match downstream
implementation and the DSC spec.

Subject: drm/msm/dsi: update hdisplay calculation for dsi_timing_setup

Currently, hdisplay is being divided by 3 for DSC. However, this
calculation only works for cases where BPP = 8.

Update hdisplay calculation to be bytes_per_line / 3, so that it
accounts for cases where BPP != 8.

Subject: drm/msm/dpu: add support for DSC encoder v1.2 engine

Add support for DSC 1.2 by providing the necessary hooks to program
the DPU DSC 1.2 encoder.

Changes in v3:
-- fixed kernel test rebot report that "__iomem *off" is declared but not
   used at dpu_hw_dsc_config_1_2()
-- unrolling thresh loops

Changes in v4:
-- delete DPU_DSC_HW_REV_1_1
-- delete off and used real register name directly

Changes in v7:
-- replace offset with sblk->enc.base
-- replace ss with slice

Changes in v8:
-- fixed checkpatch warning

Changes in v9:
-- replaced __dsc_calc_ob_max_addr() with __dsc_calc_output_buf_max_addr()
-- replaced variable num_ss with num_softslice
-- remove inline from function  declaration

changes in v10:
-- rewording text of changes in v9
-- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN
-- replace drm_dsc_calculate_flatness_det_thresh() with drm_dsc_flatness_det_thresh()

From 0d1b10c633468e84e64412b8061f6f7f678f14cb Mon Sep 17 00:00:00 2001
From: Abhinav Kumar

Subject: drm/msm/dpu: add DSC 1.2 hw blocks for relevant chipsets

Add DSC 1.2 hardware blocks to the catalog with necessary sub-block and
feature flag information.  Each display compression engine (DCE) contains
dual DSC encoders so both share same base address but with its own
different sub block address.

changes in v4:
-- delete DPU_DSC_HW_REV_1_1
-- re arrange sc8280xp_dsc[]

changes in v4:
-- fix checkpatch warning

changes in v10:
-- remove hard slice from commit text
-- replace DPU_DSC_NATIVE_422_EN with DPU_DSC_NATIVE_42x_EN
-- change DSC_BLK_1_2 .len from 0x100 to 0x29c

changes in v11:
-- remove comment at DSC_BLK_1_2 marco

Subject: msm/drm/dsi: Round up DSC hdisplay calculation

Currently, when compression is enabled, hdisplay is reduced via integer
division. This causes issues for modes where the original hdisplay is
not a multiple of 3.

To fix this, use DIV_ROUND_UP to divide hdisplay.

Add a DPU INTF op to set the DCE_DATA_COMPRESS bit to enable the
DCE/DSC 1.2 datapath

Note: For now, this op is called for command mode encoders only. Changes to
set DATA_COMPRESS for video mode encoders will be posted along with DSC
v1.2 support for DP.

Subject: drm/msm/dsi: Remove incorrect references to slice_count

Currently, slice_count is being used to calculate word count and
pkt_per_line. Instead, these values should be calculated using slice per
packet, which is not the same as slice_count.

Slice count represents the number of slices per interface, and its value
will not always match that of slice per packet. For example, it is possible
to have cases where there are multiple slices per interface but the panel
specifies only one slice per packet.

Thus, use the default value of one slice per packet and remove slice_count
from the aforementioned calculations.

Fixes: 08802f515c3c ("drm/msm/dsi: Add support for DSC configuration")
Fixes: bc6b6ff8135c ("drm/msm/dsi: Use DSC slice(s) packet size to compute word count")

Subject: drm/msm: provide fb_dirty implemenation

Since commit 93e81e38e197 ("drm/fb_helper: Minimize damage-helper
overhead") the drm_fb_helper_funcs::fb_dirty helper is required for
proper dirty/damage processing. The drm/msm driver requires that to
function to let CMD panels to work. Use simplified version of
drm_fbdev_generic_helper_fb_dirty() to fix support for CMD mode panels.

Subject: drm/msm/dp: Drop aux devices together with DP controller

Using devres to depopulate the aux bus made sure that upon a probe
deferral the EDP panel device would be destroyed and recreated upon next
attempt.

But the struct device which the devres is tied to is the DPUs
(drm_dev->dev), which may be happen after the DP controller is torn
down.

Indications of this can be seen in the commonly seen EDID-hexdump full
of zeros in the log, or the occasional/rare KASAN fault where the
panel's attempt to read the EDID information causes a use after free on
DP resources.

It's tempting to move the devres to the DP controller's struct device,
but the resources used by the device(s) on the aux bus are explicitly
torn down in the error path. The KASAN-reported use-after-free also
remains, as the DP aux "module" explicitly frees its devres-allocated
memory in this code path.

As such, explicitly depopulate the aux bus in the error path, and in the
component unbind path, to avoid these issues.

Subject: drm/msm/dp: Free resources after unregistering them

The DP component's unbind operation walks through the submodules to
unregister and clean things up. But if the unbind happens because the DP
controller itself is being removed, all the memory for those submodules
has just been freed.

Change the order of these operations to avoid the many use-after-free
that otherwise happens in this code path.

Subject: drm/msm/a6xx: Move force keepalive vote removal to
 a6xx_gmu_force_off()

As pointed out by Akhil during the review process of GMU wrapper
introduction [1], it makes sense to move this write into the function
that's responsible for forcibly shutting the GMU off.

It is also very convenient to move this to GMU-specific code, so that
it does not have to be guarded by an if-condition to avoid calling it
on GMU wrapper targets.

Move the write to the aforementioned a6xx_gmu_force_off() to achieve
that. No effective functional change.

Subject: drm/msm/a6xx: Move a6xx_bus_clear_pending_transactions to a6xx_gpu

This function is responsible for telling the GPU to halt transactions
on all of its relevant buses, drain them and leave them in a predictable
state, so that the GPU can be e.g. reset cleanly.

Move the function to a6xx_gpu.c, remove the static keyword and add a
prototype in a6xx_gpu.h to accomodate for the move.

Subject: drm/msm/a6xx: Add a helper for software-resetting the GPU

Introduce a6xx_gpu_sw_reset() in preparation for adding GMU wrapper
GPUs and reuse it in a6xx_gmu_force_off().

This helper, contrary to the original usage in GMU code paths, adds
a readback+delay sequence to ensure that the reset is never deasserted
too quickly due to e.g. OoO execution going crazy.

Subject: drm/msm/a6xx: Remove both GBIF and RBBM GBIF halt on hw init

Currently we're only deasserting REG_A6XX_RBBM_GBIF_HALT, but we also
need REG_A6XX_GBIF_HALT to be set to 0.

This is typically done automatically on successful GX collapse, but in
case that fails, we should take care of it.

Also, add a memory barrier to ensure it's gone through before jumping
to further initialization.

Subject: drm/msm/a6xx: Move CX GMU power counter enablement to hw_init

Since the introduction of A6xx support, we've been enabling the CX GMU
power counter 0 in a bit of a weird spot. Move it to hw_init so that
GMU wrapper GPUs can reuse the same code paths. As a bonus, this order
makes it easier to compare mainline and downstream register access traces.

Subject: drm/msm/a6xx: Introduce GMU wrapper support

Some (particularly SMD_RPM, a.k.a non-RPMh) SoCs implement A6XX GPUs
but don't implement the associated GMUs. This is due to the fact that
the GMU directly pokes at RPMh. Sadly, this means we have to take care
of enabling & scaling power rails, clocks and bandwidth ourselves.

Reuse existing Adreno-common code and modify the deeply-GMU-infused
A6XX code to facilitate these GPUs. This involves if-ing out lots
of GMU callbacks and introducing a new type of GMU - GMU wrapper (it's
the actual name that Qualcomm uses in their downstream kernels).

This is essentially a register region which is convenient to model
as a device. We'll use it for managing the GDSCs. The register
layout matches the actual GMU_CX/GX regions on the "real GMU" devices
and lets us reuse quite a bit of gmu_read/write/rmw calls.

Subject: drm/msm/adreno: Disable has_cached_coherent in GMU wrapper
 configurations

A610 and A619_holi don't support the feature. Disable it to make the GPU stop
crashing after almost each and every submission - the received data on
the GPU end was simply incomplete in garbled, resulting in almost nothing
being executed properly. Extend the disablement to adreno_has_gmu_wrapper,
as none of the GMU wrapper Adrenos that don't support yet seem to feature it.

Subject: drm/msm/a6xx: Add support for A619_holi

A619_holi is a GMU-less variant of the already-supported A619 GPU.
It's present on at least SM4350 (holi) and SM6375 (blair). No mesa
changes are required. Add the required kernel-side support for it.

Subject: drm/msm/a6xx: Add A610 support

A610 is one of (if not the) lowest-tier SKUs in the A6XX family. It
features no GMU, as it's implemented solely on SoCs with SMD_RPM.
What's more interesting is that it does not feature a VDDGX line
either, being powered solely by VDDCX and has an unfortunate hardware
quirk that makes its reset line broken - after a couple of assert/
deassert cycles, it will hang for good and will not wake up again.

This GPU requires mesa changes for proper rendering, and lots of them
at that. The command streams are quite far away from any other A6XX
GPU and hence it needs special care. This patch was validated both
by running an (incomplete) downstream mesa with some hacks (frames
rendered correctly, though some instructions made the GPU hangcheck
which is expected - garbage in, garbage out) and by replaying RD
traces captured with the downstream KGSL driver - no crashes there,
ever.

Add support for this GPU on the kernel side, which comes down to
pretty simply adding A612 HWCG tables, altering a few values and
adding a special case for handling the reset line.

Subject: drm/msm/a6xx: Use "else if" in GPU speedbin rev matching

The GPU can only be one at a time. Turn a series of ifs into if +
elseifs to save some CPU cycles.

Subject: drm/msm/a6xx: Use adreno_is_aXYZ macros in speedbin matching

Before transitioning to using per-SoC and not per-Adreno speedbin
fuse values (need another patchset to land elsewhere), a good
improvement/stopgap solution is to use adreno_is_aXYZ macros in
place of explicit revision matching. Do so to allow differentiating
between A619 and A619_holi.

Subject: drm/msm/a6xx: Add A619_holi speedbin support

A619_holi is implemented on at least two SoCs: SM4350 (holi) and SM6375
(blair). This is what seems to be a first occurrence of this happening,
but it's easy to overcome by guarding the SoC-specific fuse values with
of_machine_is_compatible(). Do just that to enable frequency limiting
on these SoCs.

Subject: drm/msm/a6xx: Add A610 speedbin support

A610 is implemented on at least three SoCs: SM6115 (bengal), SM6125
(trinket) and SM6225 (khaje). Trinket does not support speed binning
(only a single SKU exists) and we don't yet support khaje upstream.
Hence, add a fuse mapping table for bengal to allow for per-chip
frequency limiting.
