-STM32MP1 PWR Regulators
------------------------
-
-Available Regulators in STM32MP1 PWR block are:
- - reg11 for regulator 1V1
- - reg18 for regulator 1V8
- - usb33 for the swtich USB3V3
-
-Required properties:
-- compatible: Must be "st,stm32mp1,pwr-reg"
-- list of child nodes that specify the regulator reg11, reg18 or usb33
- initialization data for defined regulators. The definition for each of
- these nodes is defined using the standard binding for regulators found at
- Documentation/devicetree/bindings/regulator/regulator.txt.
-- vdd-supply: phandle to the parent supply/regulator node for vdd input
-- vdd_3v3_usbfs-supply: phandle to the parent supply/regulator node for usb33
-
-Example:
-
-pwr_regulators: pwr@...01000 {
- compatible = "st,stm32mp1,pwr-reg";
- reg = <0x50001000 0x10>;
- vdd-supply = <&vdd>;
- vdd_3v3_usbfs-supply = <&vdd_usb>;
-
- reg11: reg11 {
- regulator-name = "reg11";
- regulator-min-microvolt = <1100000>;
- regulator-max-microvolt = <1100000>;
- };
-
- reg18: reg18 {
- regulator-name = "reg18";
- regulator-min-microvolt = <1800000>;
- regulator-max-microvolt = <1800000>;
- };
-
- usb33: usb33 {
- regulator-name = "usb33";
- regulator-min-microvolt = <3300000>;
- regulator-max-microvolt = <3300000>;
- };
-};
