Each entry is a pair of strings, the first being the connection's sink, the second being the connection's source. For this driver the first string should always be "Analog". Optional properties: - rockchip,hp-en-gpios = The phandle of the GPIO that power up/down the headphone (when the analog output is an headphone). - rockchip,hp-det-gpios = The phandle of the GPIO that detects the headphone (when the analog output is an headphone). - pinctrl-names, pinctrl-0: Please refer to pinctrl-bindings.txt Example: sound { compatible = "rockchip,rk3288-hdmi-analog"; rockchip,model = "Analog audio output"; rockchip,i2s-controller = <&i2s>; rockchip,audio-codec = <&es8388>; rockchip,routing = "Analog", "LOUT2", "Analog", "ROUT2"; rockchip,hp-en-gpios = <&gpio8 0 GPIO_ACTIVE_HIGH>; rockchip,hp-det-gpios = <&gpio7 7 GPIO_ACTIVE_HIGH>; pinctrl-names = "default"; pinctrl-0 = <&headphone>; }; |
