Some X86 tablets, which ship with Android as factory installed OS,
specify codec IRQs/GPIOS in a special Android AMCR0F28 ACPI device.

Add support for retrieving the codec IRQ from this ACPI device instead
of from the 10EC5640 device describing the codec itself and enable this
on Asus MemoPad 7 ME176C tablets.

This fixes jack-detect not working on these tablets.

Some boards have the codec IRQ hooked-up as normally, so the driver can
still do things like headset vs headphones and button-press detection,
but instead of using one of the JD pins of the codec, an external GPIO
is used to report the jack-presence switch status of the jack.

Add support for this.

On some boards where the firmware/fwnode information is in essence
read-only (x86 + ACPI boards) the i2c_client for the codec may contain
the wrong IRQ or no IRQ at all.

Since we only request the IRQ once snd_soc_component_set_jack() gets
called, allow machine drivers to override the IRQ with the proper one
through the data parameter to snd_soc_component_set_jack().

Commit 2b9c8d2b ("ASoC: rt5640: Add the HDA header support") adds
re-queuing of the jack_work on resume when rt5640->jd_src != 0.

But the jack_work will unconditionally deref rt5640->jack and that might
be NULL. E.g. the sound/soc/intel/boards/bytcr_rt5640.c machine driver
call snd_soc_component_set_jack(codec, NULL, NULL) from pre_suspend to
disable the IRQ to avoid spurious wakeups, so when rt5640_resume()
runs rt5640->jack will be NULL in this case.

Make the queueing of the work conditional on rt5640->jack instead of
on rt5640->jd_src to fix this.

This patch series adds support for the low power hibernation feature
on cs35l41. This allows the DSP memory to be retained whilst the
device enters a very low power state.

When the reset_gpio GPIO is used, it is better to put the codec
back into reset state when the driver unbinds.

Add a remove() function to accomplish that.

In the case a device can support retaining the firmware memory across
low power states it is useful for the preloader widget to only power up
whilst actually loading/unloading the core, as opposed to the normal
operation where the widget is powered for the entire time a firmware is
preloaded onto the core. Add support for this mode and a flag to enable
it.

If the Halo registers are kept in the register cache the
HALO_CORE_RESET bit will be retained as 1 after reset is triggered in
cs_dsp_halo_start_core. This will cause subsequent writes to reset
the core which is not desired. Apart from this bit the rest of the
register bits are cacheable, so for safety sake clear the bit to
ensure the cache is consistent.

It makes no sense to cache the test/user key registers, since they
require values written at specific times, mark them volatile. It is
probably best if they can't be accessed from user-space either, so
mark them precious as well.

The interrupt force, edge, polarity and debounce are all settings
applied to the IRQ rather than status bits and as such should not be
volatile.

The OTP trim values will require re-application in the event of a
cache sync and as such should not be volatile. The OTPID however
should be volatile.

The DSP scratch registers are used to read back an error/debug code
from the DSP on shutdown, as such these should be marked volatile.

Finally, add some missing defaults, add TST_FS_MON0, and allow the
DSP core control register to be cached.

Originally, the conditions for preventing reentry are not correct.
dai->component->active is not the state specifically for pcmif dai, so it
is not a correct condition to indicate the status of pcmif dai.
On the other hand, snd_soc_dai_stream_actvie() in prepare ops for both
playback and capture possibly return true at the first entry when these
two streams are opened at the same time.

In the patch, I refer to the implementation in mt8192-dai-pcm.c.
Clock and enabling bit for PCMIF are managed by DAPM, and the condition
for prepare ops is replaced by the status of dai widget.

Playback pop is observed and the root cause is the reference clock
provided by MT8195 is diabled before RT5682 finishes the control flow.

To ensure the reference clock supplied to RT5682 is disabled after RT5682
finishes all register controls. We replace BCLK with MCLK for RT5682
reference clock, and makes use of set_bias_level_post to handle MCLK
which guarantees MCLK is off after all RT5682 register access.
