+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>;
+};
