Subject: ASoC: dt-bindings: mediatek,mt8188-mt6359: add NAU8825 support
X-Git-Tag: microblaze-v6.6~24^2~15^2~82^2
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=ee02b869dcad7ba3772b58e93dd90ab4f932fac5;p=linux-2.6-microblaze.git

ASoC: dt-bindings: mediatek,mt8188-mt6359: add NAU8825 support

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.
