+Binding for Fairchild FAN53555 regulators
+
+Required properties:
+ - compatible: "fairchild,fan53555"
+ - reg: I2C address
+
+Optional properties:
+ - fairchild,suspend-regulator: regulator number to use for suspend voltages
+ possible values are either <0> or <1>
+ - fairchild,slew-rate-microvolt: slew rate to use for positive voltage
+ transistions in microvolts per us, possible values are:
+ 64000, 32000, 16000, 8000, 4000, 2000, 1000, 500
+ - vin-supply: regulator supplying the vin pin
+
+Example:
+
+ regulator at 40 {
+ compatible = "fairchild,fan53555";
+ regulator-name = "fan53555";
+ regulator-min-microvolt = <1000000>;
+ regulator-max-microvolt = <1800000>;
+ vin-supply = <&parent_reg>;
+ fairchild,suspend-regulator = <1>;
+ fairchild,slew-rate-microvolt = <64000>;
+ };
