		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>;

		It is necessary to configure three pins for both the RK809 and RK817, the three
		pins are "gpio_ts" "gpio_gt" "gpio_slp".
		The gpio_gt and gpio_ts pins support the gpio function.
		The gpio_slp pin is for controlling the pmic states, as below:
		- reset
		- power down
		- sleep
