Here is a snippet of the downstream board's DT, that is supposed to be supported by this patchset. --------------------------------------------------------------------- / { sound { compatible = "simple-audio-card"; simple-audio-card,name = "audio-card"; simple-audio-card,format = "i2s"; simple-audio-card,bitclock-master = <&dailink_master>; simple-audio-card,frame-master = <&dailink_master>; simple-audio-card,widgets = "Speaker", "Ext Spk"; simple-audio-card,audio-routing = "Ext Spk", "LINE"; simple-audio-card,cpu { sound-dai = <&ssi1>; }; dailink_master: simple-audio-card,codec { sound-dai = <&codec>; }; }; clk_ext_audio_codec: clock-codec { compatible = "fixed-clock"; #clock-cells = <0>; clock-frequency = <12288000>; }; }; &i2c1 { codec: audio-codec@1a { compatible = "dlg,da7212"; reg = <0x1a>; #sound-dai-cells = <0>; VDDA-supply = <®_2v5_audio>; VDDSP-supply = <®_5v0_audio>; VDDMIC-supply = <®_3v3_audio>; VDDIO-supply = <®_3v3_audio>; clocks = <&clk_ext_audio_codec>; clock-names = "mclk"; }; }; --------------------------------------------------------------------- This is mostly a resend of PATCHv2. There was quite a bit of discussion for the last patch. As far as I can see no better solution was found and the patch is fine as is. Sorry for the delay in sending another revision.
