Maxim MAX9759 Speaker Amplifier
===============================
Required properties:
- compatible : "maxim,max9759"
- shutdown-gpios : the gpio connected to the shutdown pin
- mute-gpios : the gpio connected to the mute pin
- gain-gpios : the 2 gpios connected to the g1 and g2 pins
Example:
max9759: analog-amplifier {
compatible = "maxim,max9759";
shutdown-gpios = <&gpio3 20 GPIO_ACTIVE_LOW>;
mute-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;
gain-gpios = <&gpio3 23 GPIO_ACTIVE_LOW>,
<&gpio3 25 GPIO_ACTIVE_LOW>;
