Amlogic Power Management Integrated Circuit (PMIC)

PMIC6 consists of a large and varied group of sub-devices (I2C Only):

Device                   Supply Names    Description
------                   ------------    -----------
pmic6-regulator         :               : LDOs & DCDCs
pmic6-pwrkey            :               : power Key
pmic6-gpio              :               : gpio
pmic6-battery           :               : battery

======

Required properties:

- compatible : Should be "amlogic,pmic6"
- reg: I2C slave address
- interrupts: the interrupt outputs of the controller
- #gpio-cells: number of cells to describe a GPIO, this should be 2.
  The first cell is the GPIO number.
  The second cell is used to specify additional options <unused>.
- gpio-controller: mark the device as a GPIO controller
- #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
  The first cell is the IRQ number.
  The second cell is the flags, encoded as the trigger masks from
  Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
- regulators: This is the list of child nodes that specify the regulator
  initialization data for defined regulators. Not all regulators for the given
  device need to be present. The definition for each of these nodes is defined
  using the standard binding for regulators found at
  Documentation/devicetree/bindings/regulator/regulator.txt.
  The regulator is matched with the regulator-compatible.

Example:
	pmic@35 {
		compatible = "amlogic,pmic6";
		reg = <0x35>;
		interrupt-parent = <&gpio_intc>;
		interrupts = <10 IRQ_TYPE_LEVEL_LOW>;
		//irq-gpio = <&gpio GPIOF_10 GPIO_ACTIVE_LOW>;
		system-power-controller;
		interrupt-controller;
		#interrupt-cells = <2>;
		gpio-controller;
		#gpio-cells = <2>;
