Hi Krzysztof, Thanks for your review first. I aplogyize for my misunderstanding to your comment. I just renamed the file name(mt8188-afe-pcm.yaml -> mt8188-afe.yaml), and I didn't notice vendor prefix should be included.

In the case, we can configure 16ch to etdm and make use of the property to disable the last two channels. mediatek,etdm-in1-chn-disabled = /bits/ 8 <0xE 0xF>; > > + uniqueItems: true > > + items: > > + minimum: 0 > > + maximum: 15 > > + > > + "^mediatek,etdm-in[1-2]-mclk-always-on-rate-hz$": > > + description: Specify etdm in mclk output rate for always on > > case. > > How is it different than assigned-clock-rates? > This includes clock enabling at init stage. > > + > > + "^mediatek,etdm-out[1-3]-mclk-always-on-rate-hz$": > > + description: Specify etdm out mclk output rate for always on > > case. > > + > > + "^mediatek,etdm-in[1-2]-multi-pin-mode$": > > + type: boolean > > + description: if present, the etdm data mode is I2S. > > + > > + "^mediatek,etdm-out[1-3]-multi-pin-mode$": > > + type: boolean > > + description: if present, the etdm data mode is I2S. > > + > > + "^mediatek,etdm-in[1-2]-cowork-source$": > > + $ref: /schemas/types.yaml#/definitions/uint32 > > + description: > > + etdm modules can share the same external clock pin.

This suggests that etdm1_out can be clock source of > etdm-in1. Or etdm1_in can be clock source of etdm-in1...

I will separate these properties in v4.
