Merge branch 'regulator-5.2' into regulator-next

- compatible		: Must be "regulator-gpio".

- regulator-name	: Defined in regulator.txt as optional, but required

			  here.

- states		: Selection of available voltages and GPIO configs.

                          if there are no states, then use a fixed regulator

- gpios			: Array of one or more GPIO pins used to select the

			  regulator voltage/current listed in "states".

- states		: Selection of available voltages/currents provided by

			  this regulator and matching GPIO configurations to

			  achieve them. If there are no states in the "states"

			  array, use a fixed regulator instead.

Optional properties:

- enable-gpio		: GPIO to use to enable/disable the regulator.

- gpios			: GPIO group used to control voltage.

- gpios-states		: gpios pin's initial states array. 0: LOW, 1: HIGH.

			  defualt is LOW if nothing is specified.

- enable-gpios		: GPIO used to enable/disable the regulator.

			  Warning, the GPIO phandle flags are ignored and the

			  GPIO polarity is controlled solely by the presence

			  of "enable-active-high" DT property. This is due to

			  compatibility with old DTs.

- enable-active-high	: Polarity of "enable-gpio" GPIO is active HIGH.

			  Default is active LOW.

- gpios-states		: On operating systems, that don't support reading back

			  gpio values in output mode (most notably linux), this

			  array provides the state of GPIO pins set when

			  requesting them from the gpio controller. Systems,

			  that are capable of preserving state when requesting

			  the lines, are free to ignore this property.

			  0: LOW, 1: HIGH. Default is LOW if nothing else

			  is specified.

- startup-delay-us	: Startup time in microseconds.

- enable-active-high	: Polarity of GPIO is active high (default is low).

- regulator-type	: Specifies what is being regulated, must be either

			  "voltage" or "current", defaults to voltage.

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>;

	};

};
