Documentation: mfd: Add DT bindings for the LP873X

Browse Source 
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 {
