The clock id limit will be extended in the future, so it would be
helpful to see the actual clock id limit in case the firmware
response has been rejected.

The while loop in raspberrypi_discover_clocks() relies on the assumption
that the id of the last clock element is zero. Because this data comes
from the Videocore firmware and it doesn't guarantuee such a behavior
this could lead to out-of-bounds access. So fix this by providing
a sentinel element.

The function raspberrypi_fw_get_rate (e.g. used for the recalc_rate
hook) can fail to get the clock rate from the firmware. In this case
we cannot return a signed error value, which would be casted to
unsigned long. Fix this by returning 0 instead.

In the original commit 9a34b45397e5 ("clk: Add support for runtime PM"),
the commit message mentioned that pm_runtime_put_sync() would be done
at the end of clk_core_unprepare(). This mirrors the operations in
clk_core_prepare() in the opposite order.
However, the actual code that was added wasn't in the order the commit
message described. Move clk_pm_runtime_put() to the end of
clk_core_unprepare() so that it is in the correct order.

In the previous commits that added CLK_OPS_PARENT_ENABLE, support for
this flag was only added to rate change operations (rate setting and
reparent) and disabling unused subtree. It was not added to the
clock gate related operations. Any hardware driver that needs it for
these operations will either see bogus results, or worse, hang.
This has been seen on MT8192 and MT8195, where the imp_ii2_* clk
drivers set this, but dumping debugfs clk_summary would cause it
to hang.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The clk core gains a new set of APIs that allow drivers to both
acquire clks and prepare and enable them at the same time. This also
comes with devm support so that drivers can make a single call to get
and prepare and enable the clk and have that all undone when their
driver is removed.
Many folks have requested this feature over the years, but we've had
disagreements about how to implement it and if it was worthwhile to
encourage drivers to use such an API.
Now it's here, so let's see how it goes.
I hope that by introducing this API we can identify drivers that would
benefit from further consolidation of clk API usage, possibly by
moving such logic to the bus layer and out of drivers altogether.
Outside of that major API update, we have the usual collection of
driver updates. A few new SoCs are supported, mostly Qualcomm and
Renesas this time around. Then we have the long tail of non-critical
fixes and minor feature additions to various clk drivers.
And finally more clk provider migration to struct clk_parent_data,
reducing boot times in the process.
Summary:
Core:
- devm helpers for clk_get() + clk_prepare() and clk_enable()
New Drivers:
- Support for the camera clock controller in Qualcomm SM8450 and the
display and gpu clock controllers in Qualcomm SM8350
- Add support for the Renesas RZ/Five SoC
Updates:
- Various fixes, new clocks and USB GDSCs are introduced for Qualcomm
IPQ8074
- Fixes to Qualcomm MSM8939 for issues introduced by inheriting the
MSM8916 GCC driver
- Support for a new type of voteable GDSCs used by Qualcomm SC8280XP
PCIe GDSCs
- Qualcomm SC8280XP pipe clocks transitioned to the new phy-mux
implementation
- Qualcomm MSM8996 GCC, RPM clock driver and some clocks in MSM8994
GCC are migrated to use clk_parent_data
- Corrected the topology for Titan (camera) GDSCs on Qualcomm SDM845
and SM8250
- Qualcomm MSM8916 gains more possible frequencies for its GP clocks.
- The GCC and tsens handling on Qualcomm MSM8960 is reworked to mimic
the design in IPQ8074 to allow the GCC driver to probe earlier.
- The regulator based mmcx supply for Qualcomm dispcc and videocc is
dropped, as the only upstream target that adapted this interface
was transitioned several kernel versions ago
- Qualcomm GDSCs found to be enabled at boot will now reflect in the
enable count of the supply, as was done with the regulator supplies
previously
- Correct adc1, nic_media and edma1's parents for NXP i.MX93
- rdiv, mfd values, the return rate in recalc_rate and add more
frequencies in the table for fracn-gppll on i.MX
- Remove Allwinner workaround logic/compatible in fixed factor code
- MediaTek clk driver cleanups
- Add reset support to more MediaTek clk drivers
- deduplicate Allwinner ccu_clks arrays
- Allwinner H6 GPU DFS support
- Adjust Allwinner Kconfig to limit choice
- Fix initconst confusion on Renesas R-Car Gen4
- Add GPT/POEG (PWM) clocks and resets on Renesas RZ/G2L
- Add PFC and WDT clocks and resets on Renesas RZ/V2M
- Add thermal, SDHI, Z (CPU core), PCIe, and HSCIF (serial) clocks on
Renesas R-Car S4-8"

CONFIG_UML_PCI_OVER_VIRTIO=y is needed to enable CONFIG_PCI=y on UML.
However, this causes test failures when running the clk tests, i.e.
$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/clk
A snippet of the particular error is:
> ok 1 - clk_gate_test_parent_rate
> ------------[ cut here ]------------
> WARNING: CPU: 0 PID: 45 at lib/logic_iomem.c:141 __raw_readl+0x9f/0xd0
This is triggered by this cast in the test:
143 ctx->fake_mem = (void __force __iomem *)&ctx->fake_reg;
this seems to work except when logic iomem is enabled, i.e.
CONFIG_INDIRECT_IOMEM=y.
As a short-term fix, explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in
drivers/clk/.kunitconfig so we can enable it for everyone else by
default in kunit.py.
The long-term fix probably requires something more complicated, like
#ifdef CONFIG_INDIRECT_IOMEM
logic_iomem_add_region(...);

while true
do

devmem 0x3001030 4 0xb0001e02
done
Script above changes the GPU_PLL multiplier register value. While the
script is running, the user should interact with the user interface.
Using this method the following results were obtained:
| Register | Name | Bits | Values | Result |
| -- | -- | -- | -- | -- |
| 0x3001030 | GPU_PLL.MULT | 15..8 | 20-62 | OK |
| 0x3001030 | GPU_PLL.INDIV | 1 | 0-1 | OK |

Currently gcc-msm8960 driver manually creates tsens platform device
manually. It would be better to follow IPQ8064 approach, where tsens
device is defined as gcc's child device in the device tree. If nothing
else, it removes gcc's dependency on QFPROM, thus allowing clock
controller to be probed earlier.
Don't create it in case there are available child nodes (tsens) inside

SoC pins. These clocks are:
GP_CLK{0, 1} : GPIO_{31, 32} (Belongs to CAMSS according to Linux)
GP_CLK_{1-3}{A, B} : GPIO_{49-51, 97, 12, 13} (Belongs to GCC itself)
GP_MN : GPIO_110 (Doesn't seem to be described in gcc,
ignored in this patch)
Those clocks may be used as e.g. PWM sources for external peripherals.
Add more frequencies to the table for those clocks so it's possible
for arbitrary peripherals to make use of them.

Sometimes calculation of d value may result in 0 because of the
rounding after integer division. This causes the following error:
[ 113.969689] camss_gp1_clk_src: rcg didn't update its configuration.
[ 113.969754] WARNING: CPU: 3 PID: 35 at drivers/clk/qcom/clk-rcg2.c:122 update_config+0xc8/0xdc
Make sure that D value is never zero.

In cases when MND is not enabled (e.g. when only Half Integer Divider is
used), setting D registers makes no effect.
Fail instead of making ineffective write.

On SM8250 two found VFE GDSC power domains shall not be operated, if
titan top is turned off, thus the former power domains will be set as
subdomains by a GDSC registration routine.
