| 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 |
