sc7180_lpass_dev_resume() logs an error if clk_bulk_prepare_enable()
fails. The clock framework already generates error logs if anything
goes wrong, so the logging in _resume() is redundant, drop it.

This patchset refactors the Rockchip I2S/TDM driver in order to
support the RK3588 SoC, and then adds the necessary compatible
string to load the driver for it.
Patch 1 rectifies a problem with the bindings where we were too
strict about requiring the rockchip,grf property. Most features
of this audio device don't need access to the GRF to function.
Patch 2 modifies the driver to adjust its behaviour to what the
changed bindings now allow, namely using most things without the
GRF.
Patch 3 and 4 are boring compatible string stuff that enables
RK3588 support. No special data is needed to initialise the
driver for this instance of the I2S/TDM IP.
The ADAU1372 contains 24bit ADCs and DACs. Allow the driver to use
its native mode which uses the same settings as the current 32 bit
mode.

The DAPM control for PGAx uses the PGA mute bit for
power management. This bit is active high but is set to
non-inverted (ie when powering, it will mute).
The ALSA control "PGA x Capture Switch" uses the active
high PGA_ENx bit, but is set to inverted. So when
enabling this switch, the PGA gets disabled.

Different generations of Intel hardware rely on different programming
sequences to enable SoundWire IP. In existing hardware, the SoundWire
interrupt is enabled with a register field in the DSP register
space. With HDaudio multi-link extensions registers, the SoundWire
interrupt will be enabled with a generic interrupt enable field in
LCTL, without any dependency on the DSP being enabled.
Add a per-chip callback following the example of the check_sdw_irq()
model already upstream.
Note that the callback is not populated yet for MeteorLake (MTL) since
the interrupts are already enabled in the init. A follow-up patch will
move the functionality to this callback after a couple of cleanups.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
Two fixes that are result of the recent discussions [1][2].
First adds missing locking around snd_pcm_stop() while the second fix
sets substream state to DISCONNECTED if any suspend/resume related
operation fails so that userspace has means to be aware that something
went wrong during said operation.
For a BE link snd_soc_link_be_hw_params_fixup() is called by
dpcm_be_dai_hw_params() to initialize the params before it passes them
to __soc_pcm_hw_params(). Then __soc_pcm_hw_params() refines params to
match the BE codec and passes that to snd_soc_dai_hw_params().
The second call of snd_soc_link_be_hw_params_fixup() within
snd_soc_dai_hw_params() was overwriting the refined params with the
original BE CPU DAI params. This would then lead to various problems,
for example passing an invalid number of channels to the codec driver
hw_params(), or enabling more AIF widgets on the codec than are actually
mapped by TDM slots.
These errors may not be noticed on a simple 1:1 link between one CPU DAI
and one codec DAI, because most likely they have the same DAI config
(though this is not necessarily true, for example if the CPU end has dummy
TDM slots to achieve a desirable BCLK).
For 1:N mappings there are likely to be multiple codecs using different
subsets of the TDM slots and this overwriting of the refined params
can cause incorrect configuration of each codec on the link.
The erroneous extra call to the BE fixup function() was introduced
by:
commit a655de808c ("ASoC: core: Allow topology to override machine
driver FE DAI link config.")
at that time, the call to the BE fixup was already done by
dpcm_be_dai_hw_params(), which was introduced several years earlier
by:
commit 01d7584cd2 ("ASoC: dpcm: Add Dynamic PCM core operations.")
The erroneous code has changed and moved to a different source file
since the patch that introduced it, so this fix patch won't directly
apply as a fix on top of code older than:
commit 8b4ba1d317 ("ASoC: soc-dai: fix up hw params only if it is
needed")
though it can be applied with some minor adjustment to code before
that patch but after:
commit aa6166c2ac ("ASoC: soc-dai: mv soc_dai_hw_params() to soc-dai")
On any tree older than that the code is in soc-pcm.c.
