+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>;
