1STM32MP1 PWR Regulators
2-----------------------
3
4Available Regulators in STM32MP1 PWR block are:
5  - reg11 for regulator 1V1
6  - reg18 for regulator 1V8
7  - usb33 for the swtich USB3V3
8
9Required properties:
10- compatible: Must be "st,stm32mp1,pwr-reg"
11- list of child nodes that specify the regulator reg11, reg18 or usb33
12  initialization data for defined regulators. The definition for each of
13  these nodes is defined using the standard binding for regulators found at
14  Documentation/devicetree/bindings/regulator/regulator.txt.
15- vdd-supply: phandle to the parent supply/regulator node for vdd input
16- vdd_3v3_usbfs-supply: phandle to the parent supply/regulator node for usb33
