+Hisilicon Hi655x Power Management Integrated Circuit (PMIC)
+
+The hardware layout for access PMIC Hi655x from AP SoC Hi6220.
+Between PMIC Hi655x and Hi6220, the physical signal channel is SSI.
+We can use memory-mapped I/O to communicate.
+
++----------------+ +-------------+
+| | | |
+| Hi6220 | SSI bus | Hi655x |
+| |-------------| |
+| |(REGMAP_MMIO)| |
++----------------+ +-------------+
+
+Required properties:
+- compatible: Should be "hisilicon,hi655x-pmic".
+- reg: Base address of PMIC on Hi6220 SoC.
+- interrupt-controller: Hi655x has internal IRQs (has own IRQ domain).
+- pmic-gpios: The GPIO used by PMIC IRQ.
+
+Example:
+ pmic: pmic@f8000000 {
+ compatible = "hisilicon,hi655x-pmic";
+ reg = <0x0 0xf8000000 0x0 0x1000>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ pmic-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;
+ }
