Documentation: mfd: Add DT bindings for the LP873X 



The lp873x series of PMICs have a bunch of regulators and a couple
of GPO(General Purpose Outputs).
Add information for the MFD and regulator drivers.

TI LP873X PMIC MFD driver



Required properties:

  - compatible:	"ti,lp8732", "ti,lp8733"

  - 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.

  - regulators:	List of child nodes that specify the regulator

			initialization data.

Example:



pmic: lp8733@60 {

	compatible = "ti,lp8733";

	reg = <0x60>;

	gpio-controller;

	#gpio-cells = <2>;



	regulators {

		lp8733_buck0: buck0 {

			regulator-name = "lp8733-buck0";

			regulator-min-microvolt = <800000>;

			regulator-max-microvolt = <1400000>;

			regulator-min-microamp = <1500000>;

			regulator-max-microamp = <4000000>;

			regulator-ramp-delay = <10000>;

			regulator-always-on;

			regulator-boot-on;

		};



		lp8733_buck1: buck1 {

			regulator-name = "lp8733-buck1";

			regulator-min-microvolt = <800000>;

			regulator-max-microvolt = <1400000>;

			regulator-min-microamp = <1500000>;

			regulator-max-microamp = <4000000>;

			regulator-ramp-delay = <10000>;

			regulator-boot-on;

			regulator-always-on;

		};



		lp8733_ldo0: ldo0 {

			regulator-name = "lp8733-ldo0";

			regulator-min-microvolt = <800000>;

			regulator-max-microvolt = <3000000>;

			regulator-boot-on;

			regulator-always-on;

		};



		lp8733_ldo1: ldo1 {

			regulator-name = "lp8733-ldo1";

			regulator-min-microvolt = <800000>;

			regulator-max-microvolt = <3000000>;

			regulator-always-on;

			regulator-boot-on;
