Instead of using higher level wrappers (udma_rchanrt/tchanrt read/write),
use the underlying register access functions directly.
This will allow changes in the higher level wrappers within the DMAengine

This patch adds the qurik to use burst transfers only
for pl330 controller, even for request with a length of 1.
Although, the correct way should be: if the peripheral request
length is 1, the peripheral should use SINGLE request, and then
notify the dmac using SINGLE mode by src/dst_maxburst with 1.
For example, on the Rockchip SoCs, all the peripherals can use
SINGLE or BURST request by setting GRF registers. it is possible
that if these peripheral drivers are used only for Rockchip SoCs.
Unfortunately, it's not, such as dw uart, which is used so widely,
and we can't set src/dst_maxburst according to the SoCs' specific
to compatible with all the other SoCs.
So, for convenience, all the peripherals are set as BURST request
by default on the Rockchip SoCs. even for request with a length of 1.
the current pl330 driver will perform SINGLE transfer if the client's
maxburst is 1, which still should be working according to chapter 2.6.6
of datasheet which describe how DMAC performs SINGLE transfers for
a BURST request. Unfortunately, it's broken on the Rockchip SoCs,
which support only matching transfers, such as BURST transfer for
BURST request, SINGLE transfer for SINGLE request.
Finally, we add the quirk to specify pl330 to use burst transfers only.

Switch driver to use MSIX mask and unmask instead of the ignore bit.
When ignore bit is cleared, we must issue an MMIO read to ensure writes
have all arrived and check and process any additional completions. The
ignore bit does not queue up any pending MSIX interrupts. The mask bit
however does. Use API call from interrupt subsystem to mask MSIX
interrupt since the hardware does not have convenient mask bit register.

Add wq drain support. When a wq is being released, it needs to wait for
all in-flight operation to complete. A device control function
idxd_wq_drain() has been added to facilitate this. A wq drain call
is added to the char dev on release to make sure all user operations are
complete. A wq drain is also added before the wq is being disabled.
A drain command can take an unpredictable period of time. Interrupt support
for device commands is added to allow waiting on the command to
finish. If a previous command is in progress, the new submitter can block
until the current command is finished before proceeding. The interrupt
based submission will submit the command and then wait until a command
completion interrupt happens to complete. All commands are moved to the
interrupt based command submission except for the device reset during
probe, which will be polled.

According to the datasheet of pl330:
Example 2-1 Using DMAGO with the debug instruction registers
1. Create a program for the DMA channel
2. Store the program in a region of system memory
3. Poll the DBGSTATUS Register to ensure that the debug is idle
4. Write to the DBGINST0 Register
5. Write to the DBGINST1 Register
6. Write zero to the DBGCMD Register
so, we should make sure the debug is idle before step 4/5/6, not
only step 6. if not, there maybe a risk that fail to write DBGINST0/1.

The cookie tracking in dmaengine expects all submissions completed in
order. Some DMA devices like Intel DSA can complete submissions out of
order, especially if configured with a work queue sharing multiple DMA
engines. Add a status DMA_OUT_OF_ORDER that tx_status can be returned for
those DMA devices. The user should use callbacks to track the completion
rather than the DMA cookie. This would address the issue of dmatest
complaining that descriptors are "busy" when the cookie count goes
backwards due to out of order completion. Add DMA_COMPLETION_NO_ORDER
DMA capability to allow the driver to flag the device's ability to complete
operations out of order.

This reverts commit a43a67a2d715540c1368b9501a22b0373b5874c0.
This patch reverts the main part of switching direct io implementation
to iomap infrastructure. There's a problem in invalidate page that
couldn't be solved as regression in this development cycle.
The problem occurs when buffered and direct io are mixed, and the ranges
overlap. Although this is not recommended, filesystems implement
measures or fallbacks to make it somehow work. In this case, fallback to
buffered IO would be an option for btrfs (this already happens when
direct io is done on compressed data), but the change would be needed in
the iomap code, bringing new semantics to other filesystems.
Another problem arises when again the buffered and direct ios are mixed,
invalidation fails, then -EIO is set on the mapping and fsync will fail,
though there's no real error.
There have been discussions how to fix that, but revert seems to be the
least intrusive option.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f6447274f ("net: ethernet: ti: ale: fix

Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

I'm not convinced the script makes useful automaed help lines anyway,
but since we're trying to deprecate the use of "---help---" in Kconfig
files, let's fix the doc example code too.
See commit a7f7f6248d97 ("treewide: replace '---help---' in Kconfig
files with 'help'")

Pull more SCSI updates from James Bottomley:
"This is the set of changes collected since just before the merge
window opened. It's mostly minor fixes in drivers.
The one non-driver set is the three optical disk (sr) changes where
two are error path fixes and one is a helper conversion.
The big driver change is the hpsa compat_alloc_userspace rework by Al
so he can kill the remaining user. This has been tested and acked by
the maintainer"

Pull i2c updates from Wolfram Sang:
"I2C has quite some patches for you this time. I hope it is the move to
per-driver-maintainers which is now showing results. We will see.
The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
larger refactoring of the Designware, Tegra, and PXA drivers, the
Cadence driver supports being a slave now, and there is support to
instanciate SPD eeproms for well-known cases (which will be
user-visible because the i801 driver supports it), and some
devm_platform_ioremap_resource() conversions which blow up the
diffstat.
Note that I applied the Nuvoton driver quite late, so some minor fixup
patches arrived during the merge window. I chose to apply them right
away because they were trivial"
