+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)
I wouldn't have expected the gains to be available as a device tree setting.
+- 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
