1Maxim MAX8952 voltage regulator
2
3Required properties:
4- compatible: must be equal to "maxim,max8952"
5- reg: I2C slave address, usually 0x60
6- max8952,dvs-mode-microvolt: array of 4 integer values defining DVS voltages
7  in microvolts. All values must be from range <770000, 1400000>
8- any required generic properties defined in regulator.txt

10Optional properties:
11- max8952,vid-gpios: array of two GPIO pins used for DVS voltage selection
12- max8952,en-gpio: GPIO used to control enable status of regulator
13- max8952,default-mode: index of default DVS voltage, from <0, 3> range
14- max8952,sync-freq: sync frequency, must be one of following values:
15    - 0: 26 MHz
16    - 1: 13 MHz
17    - 2: 19.2 MHz
18  Defaults to 26 MHz if not specified.
19- max8952,ramp-speed: voltage ramp speed, must be one of following values:
20    - 0: 32mV/us
21    - 1: 16mV/us
22    - 2: 8mV/us
23    - 3: 4mV/us
24    - 4: 2mV/us
25    - 5: 1mV/us
26    - 6: 0.5mV/us
27    - 7: 0.25mV/us
28  Defaults to 32mV/us if not specified.
