TI LP87565 PMIC MFD driver

Required properties:
  - compatible:	"ti,lp87565", "ti,lp87565-q1"
  - reg:		I2C slave address.
  - gpio-controller:	Marks the device node as a GPIO Controller.
  - #gpio-cells:	Should be two.  The first cell is the pin number and
			the second cell is used to specify flags.
			See ../gpio/gpio.txt for more information.
  - xxx-in-supply:	Phandle to parent supply node of each regulator
			populated under regulators node. xxx should match
			the supply_name populated in driver.
Example:

lp87565_pmic: pmic@60 {
	compatible = "ti,lp87565-q1";
	reg = <0x60>;
	gpio-controller;
	#gpio-cells = <2>;

	buck10-in-supply = <&vsys_3v3>;
	buck23-in-supply = <&vsys_3v3>;

	regulators: regulators {
		buck10_reg: buck10 {
			/* VDD_MPU */
			regulator-name = "buck10";
			regulator-min-microvolt = <850000>;
			regulator-max-microvolt = <1250000>;
			regulator-always-on;
			regulator-boot-on;
		};

		buck23_reg: buck23 {
			/* VDD_GPU */
			regulator-name = "buck23";
			regulator-min-microvolt = <850000>;
			regulator-max-microvolt = <1250000>;
			regulator-boot-on;
			regulator-always-on;
		};
	};
};

TI LP87561 PMIC:

This is a single output 4-phase regulator configuration

Required properties:
  - compatible:	"ti,lp87561-q1"
  - reg:		I2C slave address.
  - gpio-controller:	Marks the device node as a GPIO Controller.
  - #gpio-cells:	Should be two.  The first cell is the pin number and
			the second cell is used to specify flags.
			See ../gpio/gpio.txt for more information.
  - xxx-in-supply:	Phandle to parent supply node of each regulator
			populated under regulators node. xxx should match
			the supply_name populated in driver.
Example:

lp87561_pmic: pmic@62 {
	compatible = "ti,lp87561-q1";
	reg = <0x62>;
	gpio-controller;
	#gpio-cells = <2>;

	buck3210-in-supply = <&vsys_3v3>;

	regulators: regulators {
		buck3210_reg: buck3210 {
			/* VDD_CORE */
			regulator-name = "buck3210";
			regulator-min-microvolt = <800000>;
			regulator-max-microvolt = <800000>;
			regulator-always-on;
			regulator-boot-on;
		};
	};
};
