The data conversion is done rather by a wrong function. We convert to
BE32, not from BE32. Although the end result must be same, this was
complained by the compiler.
Fix the code again and align with another similar function
tas2563_apply_calib() that does already right.

Some of these laptop models have quirk IDs that are identical but have
different amplifier parts fitted, this difference is described in the
ACPI information.
The solution introduced for this product family can derive the required
component binding information from ACPI instead of hardcoding it,
supports the new variants of the CS35L56 being used and has generalized
naming that makes it applicable to other ALC+amp combinations.

Fix noise from speakers connected to AUX port when no sound is playing.
The problem occurs because the `alc_shutup_pins` function includes
a 0x10ec0257 vendor ID, which causes noise on Lenovo IdeaPad 3 15IAU7 with
Realtek ALC257 codec when no sound is playing.

The recent addition of a sanity check for a too low start tick time
seems breaking some applications that uses aloop with a certain slave

With PREEMPT_RT enabled a spinlock_t becomes a sleeping lock.
This is usually not a problem with spinlocks used in IRQ context since
IRQ handlers get threaded. However, if IRQF_ONESHOT is set, the primary
handler won't be force-threaded and runs always in hardirq context. This is
a problem because spinlock_t requires a preemptible context on PREEMPT_RT.
In this particular instance, regmap mmio uses spinlock_t to protect the
register access and IRQF_ONESHOT is set on the IRQ. In this case, it is
actually better to do everything in threaded handler and it solves the
problem with PREEMPT_RT.

At the code refactoring of USB-audio quirk handling, I assumed that
the quirk entries of Stanton ScratchAmp devices were only about the
device name, and moved them completely into the rename table.
But it seems that the device requires the quirk entry so that it's
probed by the driver itself.
This re-adds back the quirk entries of ScratchAmp, but in a
minimalistic manner.

Use the late-read buffer in the CS35L56 SoundWire interface to
read OTP memory.
The OTP memory has a longer access latency than chip registers
and cannot guarantee to return the data value in the SoundWire
control response if the bus clock is >4.8 MHz. The Cirrus
SoundWire peripheral IP exposes the bridge-to-bus read buffer
and status bits. For a read from OTP the bridge status bits are
polled to wait for the OTP data to be loaded into the read buffer
and the data is then read from there.

that this device uses the older register layout.

A number of laptops have gone to market with old firmware versions that

When the CS35L41 loads its firmware, it has a number of controls to
affect its behaviour. Currently, these controls are exposed as ALSA
Controls.
These controls were never intended to be exposed to users but the
firmware doesn't mark them hidden, so make the driver ignore them.
Any changes in the coefficients handled by these controls needs to
be matched to the individual system by SSID, which is already handled
using the tuning file, when firmware is loaded, so UCM should not be
setting these controls anyway.

The microphone/speaker privacy shutter ALSA control handlers need to
call pm_runtime_resume, since the hardware needs to be powered up to
check the hardware state of the shutter. The IRQ handler for the
shutters also needs to notify the ALSA control to inform user-space
the shutters updated. However this leads to a mutex inversion,
between the sdw_dev_lock and the controls_rwsem.
To avoid this mutex inversion cache the kctl pointers before the IRQ
handler, which avoids the need to lookup the control and take the
controls_rwsem.

The recent regression report revealed that the use of WC pages for AMD
HDMI device together with AMD IOMMU leads to unexpected truncation or
noises. The issue seems triggered by the change in the kernel core
memory allocation that enables IOMMU driver to use always S/G
buffers. Meanwhile, the use of WC pages has been a workaround for the
similar issue with standard pages in the past. So, now we need to
apply the workaround conditionally, namely, only when IOMMU isn't in
place.
This patch modifies the workaround code to check the DMA ops at first
and apply the snoop-off only when needed.

USB-audio driver puts SNDRV_CHMAP_SL and _SR as left and right
surround channels for UAC1 channel map, respectively. But they should
have been SNDRV_CHMAP_RL and _RR; the current value *_SL and _SR are
rather "side" channels, not "surround". I guess I took those
mistakenly when I read the spec mentioning "surround left".
This patch corrects those entries to be the right channels.

RPN with 127:127 is treated as a Null RPN, just to reset the
parameters, and it's not translated to MIDI2. Although the current
code can work as is in most cases, better to implement the RPN reset
explicitly for Null message.

The UMP 1.1 spec says that an RPN/NRPN should be sent when one of the
following occurs:
* a CC 38 is received
* a subsequent CC 6 is received
* a CC 98, 99, 100, and 101 is received, indicating the last RPN/NRPN
message has ended and a new one has started
That said, we should send a partial data even if it's not fully
filled. Let's change the UMP conversion helper code to follow that
rule.

Commit 7ba5ca32fe6e ("ALSA: firewire-lib: operate for period elapse event
in process context") removed the process context workqueue from
amdtp_domain_stream_pcm_pointer() and update_pcm_pointers() to remove
its overhead.
With RME Fireface 800, this lead to a regression since
Kernels 5.14.0, causing an AB/BA deadlock competition for the
substream lock with eventual system freeze under ALSA operation:
thread 0:
* (lock A) acquire substream lock by
snd_pcm_stream_lock_irq() in
snd_pcm_status64()
* (lock B) wait for tasklet to finish by calling
tasklet_unlock_spin_wait() in
tasklet_disable_in_atomic() in
ohci_flush_iso_completions() of ohci.c
thread 1:
* (lock B) enter tasklet
* (lock A) attempt to acquire substream lock,
waiting for it to be released:
snd_pcm_stream_lock_irqsave() in
snd_pcm_period_elapsed() in
update_pcm_pointers() in
process_ctx_payloads() in
process_rx_packets() of amdtp-stream.c
? tasklet_unlock_spin_wait
</NMI>

Restore the process context work queue to prevent deadlock
AB/BA deadlock competition for ALSA substream lock of

and snd_pcm_stream_lock_irqsave() in snd_pcm_period_elapsed().

Merge series from Shengjiu Wang <shengjiu.wang@nxp.com>:
There are some register difference for i.MX8 and i.MX9
REG_MICFIL_FIFO_CTRL definition is updated.
REG_MICFIL_FSYNC_CTRL, REG_MICFIL_VERID, REG_MICFIL_PARAM are added from
i.MX9.

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:
Incorrect mask of Soundwire ports - one bit too long/big - was passed.
Theoretically, too wide mask could cause an out of bounds read in
sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy
driver, e.g. adding incorrect number of ports via
sdw_stream_add_slave().
Not adding Cc-stable because I don't think the issue can lead to real
out-of-bounds read.
