dt-bindings: mfd: Convert lp873x.txt to json-schema 



Convert the lp873x binding to DT schema format. The gpio-controller
and #gpio-cells properties were removed from required because using
the device as a GPIO controller is optional.

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.

  - xxx-in-supply:	Phandle to parent supply node of each regulator

			populated under regulators node. xxx can be

			buck0, buck1, ldo0 or ldo1.

  - 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>;

	buck1-in-supply = <&vsys_3v3>;

	ldo0-in-supply = <&vsys_3v3>;

	ldo1-in-supply = <&vsys_3v3>;

			regulator-name = "lp8733-buck0";

			regulator-min-microvolt = <800000>;

			regulator-max-microvolt = <1400000>;
