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.

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.

Mute the device before shutdown to avoid pops and clicks for all types
of boost.

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.

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

If it's OK for Mark, I'm going to merge those to my tree for 5.18.

The patch series seem inapplicable via git am.
Could you check the setup of your mailer?

Hi,
Could you explain how you apply this series? So I can reproduce it and see what's going on.
To apply a series of patches I usually:
1 - Find the patch series on https://patchwork.kernel.org/
2 - Click the series button on the right top corner, which will give me the single patch file with all series changes
3 - git am ~/Downloads/Support-external-boost-at-CS35l41-ASoC-driver.patch
And that works fine for me here.
Thanks
Lucas

Maybe your patch base isn't aligned with the current upstream.
Could you rebase to 5.18-rc2?
