Fixed Voltage regulator
|
|
|
|
Binding:
|
|
The binding is done by the property "compatible" - this is different, than for
|
|
binding by the node prefix (doc/device-tree-bindings/regulator/regulator.txt).
|
|
|
|
Required properties:
|
|
- compatible: "regulator-fixed"
|
|
- regulator-name: this is required by the regulator uclass
|
|
|
|
Optional properties:
|
|
- gpio: GPIO to use for enable control
|
|
- regulator constraints (binding info: regulator.txt)
|
|
|
|
Other kernel-style properties, are currently not used.
|
|
|
|
Note:
|
|
For the regulator constraints, driver expects that:
|
|
- regulator-min-microvolt is equal to regulator-max-microvolt
|
|
- regulator-min-microamp is equal to regulator-max-microamp
|
|
|
|
Example:
|
|
fixed_regulator@0 {
|
|
/* Mandatory */
|
|
compatible = "regulator-fixed";
|
|
regulator-name = "LED_3.3V";
|
|
|
|
/* Optional: */
|
|
gpio = <&gpc1 0 GPIO_ACTIVE_LOW>;
|
|
|
|
/* Optional for regulator uclass */
|
|
regulator-min-microvolt = <3300000>;
|
|
regulator-max-microvolt = <3300000>;
|
|
regulator-min-microamp = <15000>;
|
|
regulator-max-microamp = <15000>;
|
|
regulator-always-on;
|
|
regulator-boot-on;
|
|
};
