+SSM2518 audio amplifier
+
+This device supports I2C only.
+
+Required properties:
+  - compatible : Must be "adi,ssm2518"
+  - reg : the I2C address of the device. This will either be 0x34 (ADDR pin low)
+        or 0x35 (ADDR pin high)
+
+Optional properties:
+  - gpios : GPIO connected to the nSD pin. If the property is not present it is
+                assumed that the nSD pin is hardwired to always on.
+
+Example:
+
+        ssm2518: ssm2518@34 {
+                compatible = "adi,ssm2518";
+                reg = <0x34>;
+                gpios = <&gpio 5 0>;
+        };
