1 | * Maxim MAX8973 Voltage Regulator |
2 | ||
3 | Required properties: | |
4 | ||
f986c356 | 5 | - compatible: must be "maxim,max8973" |
42dc3023 GL |
6 | - reg: the i2c slave address of the regulator. It should be 0x1b. |
7 | ||
8 | Any standard regulator properties can be used to configure the single max8973 | |
9 | DCDC. | |
10 | ||
c2ffa973 LD |
11 | Optional properties: |
12 | ||
13 | -maxim,externally-enable: boolean, externally control the regulator output | |
14 | enable/disable. | |
69eb0980 LD |
15 | -maxim,enable-gpio: GPIO for enable control. If the valid GPIO is provided |
16 | then externally enable control will be considered. | |
c2ffa973 LD |
17 | -maxim,dvs-gpio: GPIO which is connected to DVS pin of device. |
18 | -maxim,dvs-default-state: Default state of GPIO during initialisation. | |
19 | 1 for HIGH and 0 for LOW. | |
20 | -maxim,enable-remote-sense: boolean, enable reote sense. | |
21 | -maxim,enable-falling-slew-rate: boolean, enable falling slew rate. | |
22 | -maxim,enable-active-discharge: boolean: enable active discharge. | |
23 | -maxim,enable-frequency-shift: boolean, enable 9% frequency shift. | |
24 | -maxim,enable-bias-control: boolean, enable bias control. By enabling this | |
25 | startup delay can be reduce to 20us from 220us. | |
