1*4882a593SmuzhiyunSSM2518 audio amplifier
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThis device supports I2C only.
4*4882a593Smuzhiyun
5*4882a593SmuzhiyunRequired properties:
6*4882a593Smuzhiyun  - compatible : Must be "adi,ssm2518"
7*4882a593Smuzhiyun  - reg : the I2C address of the device. This will either be 0x34 (ADDR pin low)
8*4882a593Smuzhiyun	or 0x35 (ADDR pin high)
9*4882a593Smuzhiyun
10*4882a593SmuzhiyunOptional properties:
11*4882a593Smuzhiyun  - gpios : GPIO connected to the nSD pin. If the property is not present it is
12*4882a593Smuzhiyun	        assumed that the nSD pin is hardwired to always on.
