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>;
};

Analog Devices SSM4567 audio amplifier
This device supports I2C only.
Required properties:
- compatible : Must be "adi,ssm4567"
- reg : the I2C address of the device. This will either be 0x34 (LR_SEL/ADDR connected to AGND),
0x35 (LR_SEL/ADDR connected to IOVDD) or 0x36 (LR_SEL/ADDR open).
Example:
ssm4567: ssm4567@34 {
compatible = "adi,ssm4567";
reg = <0x34>;
};
