Where is the DTS? Where are driver changes?

Best regards,

Hi Krzysztof:

Can I modify it to the following form:
properties:
  compatible:
    oneOf:
      - enum:
        - mediatek,mt2701-dpi
        - mediatek,mt7623-dpi
        - mediatek,mt8173-dpi
        - mediatek,mt8183-dpi
        - mediatek,mt8186-dpi
        - mediatek,mt8192-dpi
        - mediatek,mt8195-dp-intf
      - items:
          - enum:
              - mediatek,mt8188-dp-intf
          - const: mediatek,mt8195-dp-intf

This means that mt8188 reuses mt8195, so there is no need to add
compatible to the driver.

LiangXu

I am now confused. You send some bindings which do not match DTS and driver?

This has to stop... please post the bindings with the user - DTS and
optionally driver.

Best regards,
Krzysztof

Hi Krzysztof:

I'm very sorry that my patch made you confused, please ignore this
patch. I will wait for the patch of mt8188 dts to be ready and send it
together. In the later mt8188 dts, I will reuse the compatible of
mt8195.

Best Regards,
LiangXu
