OK.

I will remove the item in V2, because it's still not supported in the current code base. Next time I will remove the description, when I add common properties. > > + > > + mediatek,topckgen: > > + $ref: "/schemas/types.yaml#/definitions/phandle" > > Don't need quotes. > Did you mean I should delete this line, and only leave description here? > > + description: The phandle of the mediatek topckgen controller > > + > > + mediatek,infracfg: > > + $ref: "/schemas/types.yaml#/definitions/phandle" > > + description: The phandle of the mediatek infracfg controller > > + > > + power-domains: > > + maxItems: 1 > > + > > + clocks: > > + items: > > + - description: 26M clock > > + - description: audio pll1 clock > > + - description: audio pll2 clock > > + - description: clock divider for i2si1_mck > > + - description: clock divider for i2si2_mck > > + - description: clock divider for i2so1_mck > > + - description: clock divider for i2so2_mck > > + - description: clock divider for dptx_mck > > + - description: a1sys hoping clock > > + - description: audio intbus clock > > + - description: audio hires clock > > + - description: audio local bus clock > > + - description: mux for dptx_mck > > + - description: mux for i2so1_mck > > + - description: mux for i2so2_mck > > + - description: mux for i2si1_mck > > + - description: mux for i2si2_mck > > + - description: audio 26m clock > > + > > + clock-names: > > + items: > > + - const: clk26m > > + - const: apll1_ck > > + - const: apll2_ck > > + - const: apll12_div0 > > + - const: apll12_div1 > > + - const: apll12_div2 > > + - const: apll12_div3 > > + - const: apll12_div9 > > + - const: a1sys_hp_sel > > + - const: aud_intbus_sel > > + - const: audio_h_sel > > + - const: audio_local_bus_sel > > + - const: dptx_m_sel > > + - const: i2so1_m_sel > > + - const: i2so2_m_sel > > + - const: i2si1_m_sel > > + - const: i2si2_m_sel > > + - const: adsp_audio26m > > + > > + mediatek,etdm-in1-chn-disabled: > > + $ref: /schemas/types.yaml#/definitions/uint8-array > > + maxItems: 16 > > + description: Specify which input channel should be disabled. > > What value disables/enables? > > items: > enum: [ ??? ] > Max channel number is 16, so the value could be 0~15 in the array. For example, when 0 and 2 are configured, the input channel 0 and channel 2 won't be put in data on memory. I will add enum: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15] here. > > + > > + mediatek,etdm-in2-chn-disabled: > > + $ref: /schemas/types.yaml#/definitions/uint8-array > > + maxItems: 16 > > + description: Specify which input channel should be disabled. > > + > > +patternProperties: > > + "^mediatek,etdm-in[1-2]-mclk-always-on-rate-hz$": > > + description: Specify etdm in mclk output rate for always on > > case. > > + > > + "^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.
