[PATCH v1 0/5] Support System Suspend and Resume for CS35L41 HDA

From: Stefan Binding
Date: Tue Oct 11 2022 - 10:37:06 EST

The CS35L41 HDA driver currently only supports runtime suspend and resume.
Add support for system suspend and resume into the CS35L41 HDA driver.
The driver will put the parts into a state where they can be powered down
during suspend, and on system resume, it will restore the part.
If firmware was previously loaded, during system suspend, the firmware will
be unloaded, and during system resume, it will be loaded again.

Note: System suspend is only supported for models which use Internal Boost,
or models which use External Boost with a Boost Enable GPIO.

The chain also contains minor bug fixes for the CS35L41 HDA driver, and
associated hda_cs_dsp_ctl driver.
