| * Maxim MAX8973 Voltage Regulator |
| |
| Required properties: |
| |
| - compatible: must be "maxim,max8973" |
| - reg: the i2c slave address of the regulator. It should be 0x1b. |
| |
| Any standard regulator properties can be used to configure the single max8973 |
| DCDC. |
| |
| Optional properties: |
| |
| -maxim,externally-enable: boolean, externally control the regulator output |
| enable/disable. |
| -maxim,enable-gpio: GPIO for enable control. If the valid GPIO is provided |
| then externally enable control will be considered. |
| -maxim,dvs-gpio: GPIO which is connected to DVS pin of device. |
| -maxim,dvs-default-state: Default state of GPIO during initialisation. |
| 1 for HIGH and 0 for LOW. |
| -maxim,enable-remote-sense: boolean, enable reote sense. |
| -maxim,enable-falling-slew-rate: boolean, enable falling slew rate. |
| -maxim,enable-active-discharge: boolean: enable active discharge. |
| -maxim,enable-frequency-shift: boolean, enable 9% frequency shift. |
| -maxim,enable-bias-control: boolean, enable bias control. By enabling this |
| startup delay can be reduce to 20us from 220us. |
| |
| Example: |
| |
| max8973@1b { |
| compatible = "maxim,max8973"; |
| reg = <0x1b>; |
| |
| regulator-min-microvolt = <935000>; |
| regulator-max-microvolt = <1200000>; |
| regulator-boot-on; |
| regulator-always-on; |
| }; |
