+Bindings for Qualcomm WSA8810/WSA8815 Class-D Smart Speaker Amplifier
+
+WSA8810 is a class-D smart speaker amplifier and WSA8815 is a high-output
+power class-D smart speaker amplifier. This amplifier uses SoundWire
+digital audio as primary interface.
+
+Required properties with SoundWire Interface:
+
+- compatible:		Should be textual representation of SoundWire Enumeration
+			address.
+			Refer to soundwire/bus.txt for details.
+			Should be "sdw10,0217,2010,0" for WSA8810
+- sdw-instance-id:	Should be ('Instance ID') from SoundWire Enumeration
+		    	address.
+			Refer to soundwire/bus.txt for details.
+- pd-gpios: 		Should be phandle and gpio pair for
+			Powerdown/Shutdown pin.
+- #thermal-sensor-cells: Should be 0 
+
+Example:
+
+spkr_left:wsa8810-left{
+	compatible = "sdw10,0217,2010,0";
+	sdw-instance-id = <1>;
+	#thermal-sensor-cells = <0>;
+	...
+};
