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>; };
