Instead of a compatible value its node must be named "audio-codec". Required properties for the audio-codec subnode: - #sound-dai-cells = <1>; The audio-codec provides two DAIs. The first one is connected to the Stereo HiFi DAC and the second one is connected to the Voice DAC. Example: &mcspi1 { cpcap: pmic@0 { compatible = "motorola,cpcap", "ste,6556002"; reg = <0>; /* cs0 */ interrupt-parent = <&gpio1>; interrupts = <7 IRQ_TYPE_EDGE_RISING>; interrupt-controller; #interrupt-cells = <2>; #address-cells = <1>; #size-cells = <0>; spi-max-frequency = <3000000>; spi-cs-high; audio-codec { #sound-dai-cells = <1>; /* HiFi */ port@0 { endpoint { remote-endpoint = <&cpu_dai1>; }; }; /* Voice */ port@1 { endpoint { remote-endpoint = <&cpu_dai2>; }; }; }; }; }; |
