| 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@50001000 { |
| 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>; |
| }; |
| }; |
