- 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
- - startup-delay-us: startup time in microseconds
- - regulator constraints (binding info: regulator.txt)
- - enable-active-high: Polarity of GPIO is Active high. If this property
- is missing, the default assumed is Active low.
- 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;
- enable-active-high;
- };
