[PATCH v4 00/16] Support external boost at CS35l41 ASoC driver
Move the support for CS35L41 external boost to its shared library for ASoC use. This move resulted in cs35l41_hda_reg_sequence being removed, and its steps were broken down into regmap writes or functions from the library. And hardware configuration struct was unified for its use in the shared lib. While at it, some minor bugs were found and fixed it.
v4 changelog: - Separated GPIO 1 and 2 function enums
v3 changelog: - Remove patches already accepted - Improved logic in documentation patch - Documentation patch goes before its code - Fixed missing Signed-off-by - Fixed subject for HDA patches
v2 changelog: - Instead of removing the log, playback actions will log the last regmap access. - Documentation patch with the correct subject line and fixed bug reported by Rob Herring on the provided example.

Both ASoC and HDA require to configure the GPIOs and Boost, so create a single shared struct for hardware configuration.

Replace vspk_always_on by a enum that better characterizes the boost type, as there is 3 types of boost hardware. And with the new boost type other parts of the driver can better handle the configuration of the chip.

To facilitate the configuration of external boost devices, put all devices, with or without VSPK switch, into safe mode from the start. That allows the following parts of the driver to handle all external boost devices in the same way.

Internal Boost enable is the default option from reset, but with external boost support, internal boost must be disabled. Add the enable of internal boost in cs35l41_boost_config to centralize the internal boost configuration.

Having CS35L41_PWR_CTRL2 on cs35l41_hda_config overwrites the boost configuration for internal boost. So move it to the initialization part and use regmap_update_bits to only change the correct bits.

For each case, only log the last regmap access, so it doesn't get overwritten, and as all regmap access should show the same issues logging the last one should be enough. Change to dev_err to log this error.
Also, differentiate between a regmap access failure and invalid playback action.

External boost enables sequences for devices with or without GPIO1 as VSPK switch are the same if devices are put in safe mode from reset. As a previous patch put all external boost devices into safe mode from reset, all external boost devices can be handled in the same way for stream open and close.
The only difference is that devices without an VSPK switch can not be put in reset and devices with it can be put into reset if a configuration is applied. The function cs35l41_hda_safe_reset is created to handle the safe reset of the chip, and as systems without VSPK switch are not supported anymore, only the CS35L41 HDA driver should check its return.

Move the support for CS35L41 external boost to its shared library for ASoC use. This move resulted in cs35l41_hda_reg_sequence being removed, and its steps were broken down into regmap writes or functions from the library. And hardware configuration struct was unified for its use in the shared lib. While at it, some minor bugs were found and fixed it.
v4 changelog:
- Separated GPIO 1 and 2 function enums
v3 changelog:
- Remove patches already accepted
- Improved logic in documentation patch
- Documentation patch goes before its code
- Fixed missing Signed-off-by
- Fixed subject for HDA patches
v2 changelog:
- Instead of removing the log, playback actions will log the last regmap access.
- Documentation patch with the correct subject line and fixed bug reported by Rob Herring on the
provided example.

The code changes look OK (but for the issue Rob reported for dt-bindings stuff).
But, could you try to use more consistent prefix for the subject lines? We don't use "sound:" prefix in general unless the patch is about (native) OSS drivers. Instead, use "ALSA:" for the general ALSA/ASoC patches. Also, "hda:" should be "ALSA: hda:" instead.
