+SSM2602 support both I2C and SPI as the configuration interface,
+the selection is made by the MODE strap-in pin.
+SSM2603 and SSM2604 only support I2C as the configuration interface.
+
+Required properties:
+
+ - compatible : One of "adi,ssm2602", "adi,ssm2603" or "adi,ssm2604"
+
+ - reg : the I2C address of the device for I2C, the chip select

+ compatible = "adi,ssm2602";
+ reg = <0x1a>;
+ };
