+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>;
+ ...
+};
