[PATCH 5/5] ASoC: dt-bindings: mediatek,mt8188-mt6359: update properties

From: Trevor Wu
Date: Wed May 17 2023 - 07:30:58 EST


Add compatible string "mediatek,mt8188-nau8825" to support new board
with nau8825 codec.

ADDA_BE is used to connect to mt6359. For the machine, it must be
fixed to the same codec and configured on the machine driver. Remove
ADDA_BE from items of link-name.

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 format, but only one dai-link builds link with codec.
