-Maxim MAX8660 voltage regulator
-
-Required properties:
-- compatible: must be one of "maxim,max8660", "maxim,max8661"
-- reg: I2C slave address, usually 0x34
-- any required generic properties defined in regulator.txt
-
-Example:
-
-	i2c_master {
-		max8660@34 {
-			compatible = "maxim,max8660";
-			reg = <0x34>;
-
-			regulators {
