+ALC5632 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+ - compatible : "realtek,alc5632"
+
+ - reg : the I2C address of the device.
+
+ - gpio-controller : Indicates this device is a GPIO controller.
+
+ - #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+
+Example:
+
+alc5632: alc5632@1e {
+ compatible = "realtek,alc5632";
+ reg = <0x1a>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+};
