-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>;
-};
