-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.
-- any available generic properties defined in regulator.txt
