* Maxim MAX8973 Voltage Regulator
Required properties:
- compatible: must be one of following:
"maxim,max8973"
"maxim,max77621".
- 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;
};
