ASoC: Fixes for v7.0
A somewhat larger set of fixes than I'd like unfortunatey, not from any
one place but rather spread out over different drivers. We've got a
bunch more fixes for the SDCA interrupt support, several relatively
minor SOF fixes, a few more driver specific fixes and a couple more AMD
quirks.
Ensure that all interrupt handlers are unregistered before the parent
regmap_irq is unregistered.
sdca_irq_cleanup() was only called from the component_remove(). If the
module was loaded and removed without ever being component probed the
FDL interrupts would not be unregistered and this would hit a WARN
when devm called regmap_del_irq_chip() during the removal of the
parent IRQ.

The STM32 SAI driver do not set the clock strobing bit (CKSTR) for DSP_A,
DSP_B and LEFT_J formats, causing data to be sampled on the wrong BCLK
edge when SND_SOC_DAIFMT_NB_NF is used.
Per ALSA convention, NB_NF requires sampling on the rising BCLK edge.
The STM32MP25 SAI reference manual states that CKSTR=1 is required for
signals received by the SAI to be sampled on the SCK rising edge.
Without setting CKSTR=1, the SAI samples on the falling edge, violating
the NB_NF convention. For comparison, the NXP FSL SAI driver correctly
sets FSL_SAI_CR2_BCP for DSP_A, DSP_B and LEFT_J, consistent with its
I2S handling.
This patch adds SAI_XCR1_CKSTR for DSP_A, DSP_B and LEFT_J in
stm32_sai_set_dai_fmt which was verified empirically with a cs47l35 codec.
RIGHT_J (LSB) is not investigated and addressed by this patch.
Note: the STM32 I2S driver (stm32_i2s_set_dai_fmt) may have the same issue
for DSP_A mode, as I2S_CGFR_CKPOL is not set. This has not been verified
and is left for a separate investigation.

Currently, the driver only performs a hardware reset during the I2C probe
sequence. To ensure all internal states of the codec are properly cleared
without affecting the configuration registers, a software reset is also
required.
According to the hardware specification, writing to the Software Reset
register (R01) twice will reset all internal states safely.
This patch adds the nau8325_software_reset() function, executes it right
after the hardware reset in the probe function, and marks the R01 register
as writeable in the regmap configuration.

Delta 410 uses snd_akm4xxx_reset() both around DFS changes and from
its PM callbacks, but the AK4529 case in this helper is still left
unimplemented and never drives the codec reset path.
The AK4529 datasheet documents register 09h.RSTN as an internal
timing reset. Clearing RSTN powers down the ADC and DAC blocks, but
does not reinitialize the register map. That matches the existing
ak4xxx helper model, which already keeps the desired codec state in
the software register cache.
Implement AK4529 reset handling by clearing 09h.RSTN on state == 1,
then replaying the cached register image and setting RSTN back to 1
on state == 0.
This restores cached Delta 410 mixer state after resume and gives
the AK4529 DFS-change path a real codec reset sequence.

The InterWave STB variant uses a TEA6330T mixer on its private
I2C bus. The mixer state is cached in software, but there is no
helper to push that register image back to hardware after system
resume.
Add a small restore helper that reapplies the cached TEA6330T
register image to the device so board drivers can restore the
external mixer state as part of their PM resume path.
Take snd_i2c_lock() around the full device lookup and restore
sequence so the bus device list traversal is also protected.

Bard Liao <yung-chuan.liao@linux.intel.com> says:
To make sure find_acpi_adr_device can work well when some of the
endpoints are missing and do not map 1:1 to codec_info_list.
IRQs are enabled through sdca_irq_populate() from component probe
using devm_request_threaded_irq(), this however means the IRQs can
persist if the sound card is torn down. Some of the IRQ handlers
store references to the card and the kcontrols which can then
fail. Some detail of the crash was explained in [1].
Generally it is not advised to use devm outside of bus probe, so
the code is updated to not use devm. The IRQ requests are not moved
to bus probe time as it makes passing the snd_soc_component into
the IRQs very awkward and would the require a second step once the
component is available, so it is simpler to just register the IRQs
at this point, even though that necessitates some manual cleanup.

gusextreme still leaves its ISA PM callbacks disabled because the shared
GF1 core had no suspend and resume path suitable for PM recovery.
Resume on this board needs one extra step before the shared GF1 path can
touch the chip again: the ES1688 side must restore the GF1 routing. Split
that routing sequence into a helper, reuse it for probe and resume, reset
the ES1688 side first on resume, and then wire the driver up to the shared
GUS PM helpers.
This restores usable post-resume GF1 operation on GUS Extreme without
rerunning probe-only detection in the shared GF1 path.

gusclassic and gusextreme still leave their ISA PM callbacks disabled
because the shared GF1 core only provides probe-time startup and full
shutdown paths.
Those helpers are not suitable for suspend and resume. They reset software
handlers and tear down runtime state such as the DRAM allocator, timer
state, DMA queues, PCM state and UART setup. Resume instead needs a
narrower recovery path that rebuilds the GF1 hardware state without
rerunning probe-only detection or discarding the bookkeeping kept by the
card instance.
Add shared GF1 suspend and resume helpers for that recovery path. Suspend
now quiesces GF1 PCM, aborts queued GF1 DMA work, resets the UART and
powers the chip down without tearing down allocator, timer or rawmidi
bookkeeping. Resume rebuilds the GF1 hardware state, restores timer and
UART handlers, and brings the chip back to a usable post-resume state for
the ISA front-ends.
The scope is limited to restoring post-resume usability. It does not
attempt transparent continuation of active GF1 PCM or synth state across
suspend, and userspace may still need to reprepare streams or reload
onboard sample data after resume. Open rawmidi substreams are restored
only to a usable post-resume state.

spdif_passthru_playback_get_resources() uses atc->pll_rate as the RSR
for the MSR calculation loop. However, pll_rate is only updated in
atc_pll_init() and not in hw_pll_init(), so it remains 0 after the
card init.
When spdif_passthru_playback_setup() skips atc_pll_init() for
32000 Hz, (rsr * desc.msr) always becomes 0, causing the loop to spin
indefinitely.
Add fallback to use atc->rsr when atc->pll_rate is 0. This reflects
the hardware state, since hw_card_init() already configures the PLL
to the default RSR.

Commit 391e69143d increased CT_PTP_NUM from 1 to 4 to support 256
playback streams, but the additional pages are not used by the card
correctly. The CT20K2 hardware already has multiple VMEM_PTPAL
registers, but using them separately would require refactoring the
entire virtual memory allocation logic.
ct_vm_map() always uses PTEs in vm->ptp[0].area regardless of
CT_PTP_NUM. On AMD64 systems, a single PTP covers 512 PTEs (2M). When
aggregate memory allocations exceed this limit, ct_vm_map() tries to
access beyond the allocated space and causes a page fault:

onyx_prepare() accepts 32/44.1/48 kHz PCM playback, but it leaves the
Onyx IEC958 sample-rate status bits at the driver's initial 44.1 kHz
setting in DIG_INFO3. As a result, 32 kHz and 48 kHz PCM streams
advertise a stale IEC958 sample rate unless userspace rewrites IEC958
Playback Default first.
Update only the consumer sample-frequency bits in DIG_INFO3 from the PCM
runtime during prepare, resolving the long-standing FIXME in the PCM
playback path while leaving the other user-controlled IEC958 status bits
unchanged.
Mark IEC958 Playback Default as volatile as well, since prepare() now
changes the exposed register contents outside the control put callback.
