It has RX and TX Soundwire devices. The WCD9390/WCD9395 IC has a functionally separate USB-C Mux subsystem accessible over an I2C interface. The Audio Headphone and Microphone data path between the Codec and the USB-C Mux subsystems are external to the IC, thus requiring DT port-endpoint graph description to handle USB-C altmode & orientation switching for Audio Accessory Mode. allOf: - $ref: dai-common.yaml# - $ref: qcom,wcd93xx-common.yaml# properties: compatible: oneOf: - const: qcom,wcd9390-codec - items: - const: qcom,wcd9395-codec - const: qcom,wcd9390-codec mode-switch: description: Flag the port as possible handler of altmode switching type: boolean orientation-switch: description: Flag the port as possible handler of orientation switching type: boolean port: $ref: /schemas/graph.yaml#/properties/port description: A port node to link the WCD939x Codec node to USB MUX subsystems for the purpose of handling altmode muxing and orientation switching to detect and enable Audio Accessory Mode. required: - compatible unevaluatedProperties: false examples: - | #include codec { compatible = "qcom,wcd9390-codec"; reset-gpios = <&tlmm 32 GPIO_ACTIVE_LOW>; #sound-dai-cells = <1>; qcom,tx-device = <&wcd939x_tx>; qcom,rx-device = <&wcd939x_rx>; qcom,micbias1-microvolt = <1800000>; qcom,micbias2-microvolt = <1800000>; qcom,micbias3-microvolt = <1800000>; qcom,micbias4-microvolt = <1800000>; qcom,hphl-jack-type-normally-closed; qcom,ground-jack-type-normally-closed; qcom,mbhc-buttons-vthreshold-microvolt = <75000 150000 237000 500000 500000 500000 500000 500000>; qcom,mbhc-headphone-vthreshold-microvolt = <50000>; }; /* ... */ soundwire@3210000 { #address-cells = <2>; #size-cells = <0>; reg = <0x03210000 0x2000>; wcd939x_rx: codec@0,4 { compatible = "sdw20217010e00"; reg = <0 4>; qcom,rx-port-mapping = <1 2 3 4 5 6>; }; }; soundwire@3230000 { #address-cells = <2>; #size-cells = <0>; reg = <0x03230000 0x2000>; wcd938x_tx: codec@0,3 { compatible = "sdw20217010e00"; reg = <0 3>; qcom,tx-port-mapping = <2 3 4 5>; }; }; ...
