Kernel-4.18.0-80.el8_lp873x

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.
  

• 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>;

buck0-in-supply = <&vsys_3v3>;
buck1-in-supply = <&vsys_3v3>;
ldo0-in-supply = <&vsys_3v3>;
ldo1-in-supply = <&vsys_3v3>;
