In a number of debug cases, the DMA-based trace can add problems
(e.g. with HDaudio channel allocation). It also generates additional
traffic on the bus and if the DMA handling is unreliable will prevent
audio use-cases from working normally. Using the trace also requires
tools to be installed on the target.
The trace can be instead handled as dynamic debug. We can use a
Kconfig to force the trace to be enabled in all cases, or use a module
parameter to enable it on a need-basis, e.g. by setting "options
snd_sof sof_debug=0x1" in a /etc/modprobe.d file.

On stream stop currently we stop the DMA first followed by the CPU DAI.
This can cause underflow (playback) or overflow (capture) on the DAI side
as the DMA is no longer feeding data while the DAI is still active.
It can be observed easily if the DAI side does not have FIFO (or it is
disabled) to survive the time while the DMA is stopped, but still can
happen on relatively slow CPUs when relatively high sampling rate is used:
the FIFO is drained between the time the DMA is stopped and the DAI is
stopped.
It can only fixed by using different sequence within trigger for 'stop' and
'start':
case SNDRV_PCM_TRIGGER_START:
case SNDRV_PCM_TRIGGER_RESUME:
case SNDRV_PCM_TRIGGER_PAUSE_RELEASE:
Trigger order: dai_link, DMA, CPU DAI then the codec
case SNDRV_PCM_TRIGGER_STOP:
case SNDRV_PCM_TRIGGER_SUSPEND:
case SNDRV_PCM_TRIGGER_PAUSE_PUSH:
Trigger order: codec, CPU DAI, DMA then dai_link

In i.MX8QM/i.MX8QXP, the DMA is EDMA, which don't support 24bit

As of commit 648e921888 ("clk: x86: Stop marking clocks as
CLK_IS_CRITICAL"), the cht_bsw_rt5645 driver needs to enable the clock
it's using for the codec's mclk. It does this from commit 7735bce05a
("ASoC: Intel: boards: use devm_clk_get() unconditionally"), enabling
pmc_plt_clk_3. However, Strago family Chromebooks use pmc_plt_clk_0 for
the codec mclk, resulting in white noise with some digital microphones.
Add a DMI-based quirk for Strago family Chromebooks to use pmc_plt_clk_0
instead - mirroring the changes made to cht_bsw_max98090_ti in
commit a182ecd380 ("ASoC: intel: cht_bsw_max98090_ti: Add quirk for
boards using pmc_plt_clk_0") and making use of the existing

LSB-valid 16bit, MSB shift-out first, frame sync asserting with
the first bit of the frame, data shifted with the posedge of
bit clock, 44.1 kHz or 48 kHz signals from SAI1 in left justified
format; and it provides the SNR target as no more than 20dB for
the signals below 10 kHz. The signals above 10 kHz will have
worse THD+N values.
MQS provides only simple audio reproduction. No internal pop,
click or distortion artifact reduction methods are provided.

Here are 2 small Documentation/process/embargoed-hardware-issues.rst
file updates that missed my previous char/misc pull request for 5.4-rc1.
The first one adds an Intel representative for the process, and the
second one cleans up the text a bit more when it comes to how the
disclosure rules work, as it was a bit confusing to some companies.

"Fixes from the recent SMB3 Test events and Storage Developer
Conference (held the last two weeks).
Here are nine smb3 patches including an important patch for debugging
traces with wireshark, with three patches marked for stable.
Additional fixes from last week to better handle some newly discovered
reparse points, and a fix the create/mkdir path for setting the mode
more atomically (in SMB3 Create security descriptor context), and one
for path name processing are still being tested so are not included
here"

The csky_pmu.max_period has type u64, and BIT() can only return
32 bits unsigned long on C-SKY. The initialization for max_period
will be incorrect when count_width is bigger than 32.
Use BIT_ULL()

We need set fp zero to let backtrace know the end. The patch fixup perf
callchain panic problem, because backtrace didn't know what is the end
of fp.

The csky implementation of free_initrd_mem() is an open-coded version of
free_reserved_area() without poisoning.
Remove it and make csky use the generic version of free_initrd_mem().
