+Maxim MAX8952 voltage regulator

+Required properties:
+- compatible: must be equal to "maxim,max8952"
+- reg: I2C slave address, usually 0x60
+- max8952,dvs-mode-microvolt: array of 4 integer values defining DVS voltages
+ in microvolts. All values must be from range <770000, 1400000>
+- any required generic properties defined in regulator.txt
+
+Optional properties:
+- max8952,vid-gpios: array of two GPIO pins used for DVS voltage selection
+- max8952,en-gpio: GPIO used to control enable status of regulator
+- max8952,default-mode: index of default DVS voltage, from <0, 3> range
+- max8952,sync-freq: sync frequency, must be one of following values:
+ - 0: 26 MHz
+ - 1: 13 MHz
+ - 2: 19.2 MHz
+ Defaults to 26 MHz if not specified.
+- max8952,ramp-speed: voltage ramp speed, must be one of following values:
+ - 0: 32mV/us
+ - 1: 16mV/us
+ - 2: 8mV/us
+ - 3: 4mV/us
+ - 4: 2mV/us
+ - 5: 1mV/us
+ - 6: 0.5mV/us
+ - 7: 0.25mV/us
+ Defaults to 32mV/us if not specified.
