If wait_for_completion_timeout() times-out in _cdns_xfer_msg() it
is possible that something could have been written to the RX FIFO.
In this case, we should drain the RX FIFO so that anything in it
doesn't carry over and mess up the next transfer.
Obviously, if we got to this state something went wrong, and we
don't really know the state of everything. The cleanup in this
situation cannot be bullet-proof but we should attempt to avoid
breaking future transaction, if only to reduce the amount of
error noise when debugging the failure from a kernel log.
Note that this patch only implements the draining for blocking
(non-deferred) transfers. The deferred API doesn't have any proper
handling of error conditions and would need some re-design before
implementing cleanup. That is a task for a separate patch...

The command FIFOs in the Cadence IP can be configured during design
up to 32 entries, and the code in cadence_master.c was assuming the
full 32-entry FIFO. But all current Intel implementations use an 8-entry
FIFO.
Up to now the longest message used was 6 entries so this wasn't
causing any problem. But future Cirrus Logic codecs have downloadable
firmware or tuning blobs. It is more efficient for the codec driver to
issue long transfers that can take advantage of any queuing in the
Soundwire controller and avoid the overhead of repeatedly writing the
page registers.

The only thing these DAI startup/shutdown callbacks do is play with
pm_runtime reference counts.
This is not wrong, but it's not necessary at all. At the ASoC core level,
only the component matters for pm_runtime. The ASoC core already calls
pm_runtime_get_sync() in snd_soc_pcm_component_pm_runtime_get(),
before the DAI startup callback is invoked.
None of the SoundWire codec drivers rely on pm_runtime helpers in
their DAI startup/shutdown either. This adds to the evidence that only
the component, or more precisely the device specified when registering
a component, should deal with pm_runtime transitions.
Beyond the code cleanup, this move prepares for the addition of link
power management in the auxiliary device startup/resume/suspend
callbacks. The DAI callbacks can by-design assume that the device is
already pm_runtime active.

2 errors generated.
The test code tests/bpf-script-test-prologue.c uses fmode_t. And the
error above is for "fmode_t" which is defined in include/linux/types.h
as part of kernel build directory: "/lib/modules/<kernel_version>/build"
that comes from kernel devel [ soft link to /usr/src/<kernel_version> ].
Clang picks this header file from "-working-directory" build option that
specifies this build folder.
But the commit 14e4b9f428 ("perf trace: Raw augmented syscalls fix
libbpf 1.0+ compatibility") changed the include directory to use:
"/usr/include".
Post this change, types.h from /usr/include/ is getting picked upwhich
doesn’t contain definition of "fmode_t" and hence fails to compile.

The difference is addition of -I/usr/include/ in the first line which
is causing the error. Fix this by adding typedef for "fmode_t" in the
testcase to solve the compile issue.

The hardware supports the 332 8bpp and 4:4:4:4 16bpp formats,
but the table of supported formats didn't include them.
Add them in.
In theory they are supported for T-format as well as linear,
but without a way to test them just add them as linear for now.

pixel_order is used for the earlier versions of the HVS, so is
redundant on the 10:10:10:2 and 10bit YUV formats that are only
supported on HVS5.
Remove the assignment from the table to avoid confusion.

vc4_plane_mode_set for HVS5 was using pixel_order unless pixel_order_hvs5
was non-zero, except 0 is a valid value for the pixel_order.
Specify pixel_order_hvs5 for all formats and remove the conditional.

atomic_flush will be called for each CRTC even if they aren't enabled.
The whole code we have there will thus run without a properly affected
channel, which can then result in all sorts of weird behaviour.

HVS5 supports the 210101010 RGB[A|X] formats, but they were
missing from the DRM to HVS mapping list, so weren't available.
Add them in.

Same as the xRGB8888 formats, HVS5 has managed to swap the colour
channels for the xRGB1555 formats as well. Add the relevant
config for pixel_order_hvs5.
