+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

+ Refer to soundwire/slave.txt for details.
+ Should be "sdw0110217201000" for WSA8810
+
+- pd-gpios: Should be phandle and gpio pair for
+ Powerdown/Shutdown pin.
+- #thermal-sensor-cells: Should be 0
+
+Example:
+
+spkr_left:wsa8810-left{
+ compatible = "sdw0110217201000";
+ #thermal-sensor-cells = <0>;
+ ...
+};
