Add the audio codec sub-device. This sub-device is used to set the
optional voltage values according to the hardware.
The properties are:
- Setup of microphone bias voltage.
- Setup of the speaker pin pull-down.
Also, add the audio power supply property which is dedicated for
the audio codec sub-device.

Still not much improved. You do not have any resources there, so these
should go to the parent node.
Hi Krzysztof,
vaud28-supply seems to be a mistake that I forward port.
In the V4, AFAII, your feedback [1] suggested me to move the vaud28-supply from the "audio-codec"
sub-node to the parent node, which for me is the "pmic" (mfd), because the property is considered as
power-supply.
pwrap {
pmic {
...
audio-codec {
...
Hardware side, vaud28-supply is the output of PMIC-regulator subsystem, and AVDD28 is the input of
PMIC-audio-codec subsystem. Then:
- The property name is wrong and must be change to AVDD28, which is a consumer (power input), not a
power-supply. => description: 2.8 volt power input for microphones (AU_VIN0, AU_VIN1, AU_VIN2)
- IMHO, move this property to the next parent (pwrap) isn't consistent. It should be moved back to
Documentation/devicetree/bindings/mfd/mediatek,mt6357.yaml (Done in the V4) into audio-codec
substystem, beside mediatek,micbias0-microvolt
Does this sound good to you ?
