The ssm2305 is a simple Class-D audio amplifier. A application can turn on/off the device by a gpio. It's also possible to hardwire the shutdown pin.
Tested on a i.MX6 based custom board.

+Required properties:
- compatible : "adi,ssm2305"
+Optional properties:
- ssm2305,shutdown-gpio : the gpio connected to the shutdown pin
This should be called shutdown-gpios (plural, no vendor prefix) for consistency. Also, since the shutdown GPIO on SSM2305 is active low, this should be documented here.
