+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>;
