+ST TDA7802 audio processor
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : "st,tda7802"
+- reg : the I2C address of the device
+- enable-supply : a regulator spec for the PLLen pin
+
+Optional properties:
+
+- st,gain-ch13 : gain for channels 1 and 3 (range: 1-4)
+- st,gain-ch24 : gain for channels 2 and 3 (range: 1-4)
+- st,diagnostic-mode-ch13 : diagnotic mode for channels 1 and 3
+                            values: "Speaker" (default), "Booster"
+- st,diagnostic-mode-ch24 : diagnotic mode for channels 2 and 4
+                            values: "Speaker" (default), "Booster"
+
+Example:
+
+amp: tda7802@6c {
+	compatible = "st,tda7802";
+	reg = <0x6c>;
+	enable-supply = <&amp_enable_reg>;
+};
