From: Weidong Wang <[email protected]>
The awinic aw87390 is a new high efficiency, low noise,
constant large volume, 6th Smart K audio amplifier.
Add a DT schema for describing awinic aw87390 audio amplifiers.
They are controlled using I2C.
v1 -> v2 : Added properties in awinic,aw88395 file
Remove fade-enable because the functionality is
duplicated in the aw88395 driver
Modify dev_err_probe usage
Delete unused header files
Change the i2c driver name
Modify the way a function returns a value
Weidong Wang (5):
ASoC: dt-bindings: Adds properties to "awinic,aw88395"
ASoC: dt-bindings: Add schema for "awinic,aw87390"
ASoC: codecs: Add code for bin parsing compatible with aw87390
ASoC: codecs: Change the aw88261 variable name and i2c driver name
ASoC: codecs: Add aw87390 amplifier driver

The subject is still pretty generic. Ideally, we'd never have the same
subject twice. I'd do something like this:
ASoC: dt-bindings: awinic,aw88395: Add properties for multiple PA support

Complete in what way? multiple PAs, right. It's not really clear
to me though how these properties enable support for multiple PAs.

I'll add "This change is for consistency with yaml properties" to the commit message.

This change is to be consistent with the name in the yaml file

Thank you very much for your advice, and I will modify it in the next patch.

Thank you very much. I will change the following content in the next patch:
Add two properties, the "awinic,audio-channel" property and the
"awinic,sync-flag". The "awinic,audio-channel" is used to make
different PA load different configurations, the "awinic,sync-flag"
is used to synchronize the phases of multiple PA. These two properties
will be read by the corresponding driver, so that the multi-PA to
achieve better playback effect.

Looks like bool, not uint32. If you made it uint32 for some future
purpose, then the name "flag" is misleading and anyway what would be the
third option here for sync?

Thank you very much for your review, but I have a question that I would like to consult

Thank you very much. Can I Change it to "$ref: /schemas/types.yaml#/definitions/bool"?
