The mt6359-codec support these 3 properties: mediatek,mic-type0, mediatek,mic-type-1, mediatek-mic-type2. While mt6358-sound and mt6397-codec don't (at least, I didn't find these 3 properties in driver codes. Set 'additionalProperties: true' is also required to fix the following dtbs_check errors: pmic: audio-codec: 'mediatek,mic-type-0', 'mediatek,mic-type-1', 'mediatek,mic-type-2' do not match any of the regexes: 'pinctrl-[0-9]+' >> >> Signed-off-by: Macpaul Lin <macpaul.lin@mediatek.com> >> --- >> Documentation/devicetree/bindings/mfd/mediatek,mt6397.yaml | 5 +++-- >> 1 file changed, 3 insertions(+), 2 deletions(-) >> >> diff --git a/Documentation/devicetree/bindings/mfd/mediatek,mt6397.yaml b/Documentation/devicetree/bindings/mfd/mediatek,mt6397.yaml >> index 40cabaf60d0d..ffb5848a96d5 100644 >> --- a/Documentation/devicetree/bindings/mfd/mediatek,mt6397.yaml >> +++ b/Documentation/devicetree/bindings/mfd/mediatek,mt6397.yaml >> @@ -104,7 +104,7 @@ properties: >> >> audio-codec: >> type: object >> - additionalProperties: false >> + additionalProperties: true >> description: >> Audio codec support with MT6397 and MT6358. >> >> @@ -112,8 +112,9 @@ properties: >> compatible: >> oneOf: >> - enum: >> - - mediatek,mt6397-codec >> - mediatek,mt6358-sound >> + - mediatek,mt6359-codec >> + - mediatek,mt6397-codec >> - items: >> - enum: >> - mediatek,mt6366-sound >> -- >> 2.45.2 >> Thanks Macpaul Lin

I'm working on a new fix (v7) for 'Documentation/devicetree/bindings/mfd/mediatek,mt6397.yaml' and try to rid of these mess in audio-codec node. Thanks Macpaul Lin

Some fix and updates in the following items: 1. examples: Update generic node name to 'audio-codec' to comply with the coming change in 'mt6359.dtsi'. This change is necessary to fix the dtbs_check error: pmic: 'mt6359codec' does not match any of the regexes: 'pinctrl-[0-9]+' 2. mediatek,dmic-mode: After inspecting the .dts and .dtsi files using 'mt6359-codec', it was discovered that the definitions of 'two wires' and 'one wire' are inverted compared to the DT schema. For example, the following boards using MT6359 PMIC: - mt8192-asurada.dtsi - mt8195-cherry.dtsi These boards use the same definitions of 'dmic-mode' as other boards using MT6358 PMIC. The meaning of '0' or '1' has been noted as comments in the device trees. Upon examining the code in [1] and [2], it was confirmed that the definitions of 'dmic-mode' are consistent between "MT6359 PMIC" and "MT6358 PMIC". Therefore, the DT Schema should be correct as is.
