Analog Devices SSM2602, SSM2603 and SSM2604 I2S audio CODEC devices 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 number for SPI. Example: ssm2602: ssm2602@1a { compatible = "adi,ssm2602"; reg = <0x1a>; };
