      1Hisilicon Hi655x Power Management Integrated Circuit (PMIC)
      2
      3The hardware layout for access PMIC Hi655x from AP SoC Hi6220.
      4Between PMIC Hi655x and Hi6220, the physical signal channel is SSI.
      5We can use memory-mapped I/O to communicate.

     14Required properties:
     15- compatible:           Should be "hisilicon,hi655x-pmic".
     16- reg:                  Base address of PMIC on Hi6220 SoC.
     17- interrupt-controller: Hi655x has internal IRQs (has own IRQ domain).
     18- pmic-gpios:           The GPIO used by PMIC IRQ.
     19- #clock-cells:		From common clock binding; shall be set to 0
     20
     21Optional properties:
     22- clock-output-names: From common clock binding to override the
     23  default output clock name
     24
     25Example:
     26	pmic: pmic@f8000000 {
     27		compatible = "hisilicon,hi655x-pmic";
     28		reg = <0x0 0xf8000000 0x0 0x1000>;
     29		interrupt-controller;
     30		#interrupt-cells = <2>;
     31		pmic-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;
     32		#clock-cells = <0>;
