    Subject[PATCH v2 7/7] ASoC: dt-bindings: mediatek,mt8188-mt6359: add NAU8825 support
    Date
    Add compatible string "mediatek,mt8188-nau8825" to support new board
    with nau8825 codec.

    Introduce two properties "dai-format" and "mediatek,clk-provider" under
    dai-link subnode to configure dai-link parameters via dts.

    "codec" property is removed from required property of dai-link subnode.
    For co-clock case, it's possible two dai-links should be configured to
    the same dai format, but only one cpu dai is bound with codec.
