So CS35L41_MDSYNC_GPIO1 is identical with *_DRAIN_GPIO2, i.e. it's an
alias?

The value 2 sets GPIO1 as MDSYNC pin and GPIO2 as IRQ pin (Open drain).
It could be the same label, like CS35L41_GPIO1_MDSYNC_GPIO2_IRQ, but I think separating them is better for understanding the code and organizing the code.

Yes, separating GPIO1 and GPIO2 would be less confusing.

The driver can receive an empty hw_config, so mark as valid if
successfully read from device tree/ACPI or set by the driver itself.
Platforms not marked with a valid hw config will not be supported.

Just use "ALSA:" prefix for the subject instead of "sound:" in case
both ALSA HD-audio and ASoC are covered in the patch.

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.

Remove cs35l41_hd_reg_sequence as it adds a layer of flexibility not needed.
As cs35l41_hda_(start/stop)_bst is a single register, it can be replaced by
regmap_update_bits with usleep_range to wait for the same 3000us that
reg_sequence had.

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.

From: David Rhodes <drhodes@opensource.cirrus.com>
Document internal and external boost feature for ASoC CS35L41.
For internal boost the following properties are required:
- cirrus,boost-peak-milliamp
- cirrus,boost-ind-nanohenry
- cirrus,boost-cap-microfarad
For external boost, the GPIO1 must be configured as output,
so the following properties are required:
- cirrus,gpio1-src-select = <1>
- cirrus,gpio1-output-enable

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):
yamllint warnings/errors:
./Documentation/devicetree/bindings/sound/cirrus,cs35l41.yaml:152:13: [warning] wrong indentation: expected 10 but found 12 (indentation)
dtschema/dtc warnings/errors:
doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/patch/1603100
This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.

Note that this will be true if cirrus,boost-type is not present. You

Not present means Internal boost. There will be other types of boost in
the future, so I would like to keep it as is.

Yes, that's expected. We want to continue to support old device trees
without boost type, and for that case it sets to internal boost.
