+ROCKCHIP RK3288 with HDMI and analog audio
+
+Required properties:
+- compatible: "rockchip,rk3288-hdmi-analog"
+- rockchip,model: The user-visible name of this sound complex
+- rockchip,i2s-controller: The phandle of the Rockchip I2S controller that's
+ connected to the CODEC
+- rockchip,audio-codec: The phandle of the analog audio codec.
+- rockchip,routing: A list of the connections between audio components.
+ 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".
+
+Optionnal 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>;
+};
