+Hisilicon hi655x Power Management Integrated Circuit (PMIC)
+
+hi655x consists of a large and varied group of sub-devices:
+
+Device			 Supply Names	 Description
+------			 ------------	 -----------
+hi655x-powerkey		:		: Powerkey
+hi655x-regulator-pmic	:		: Regulators
+hi655x-usbvbus		:		: USB plug detection
+hi655x-pmu-rtc		:		: RTC
+hi655x-coul		:		: Coulomb
+
+Required properties:
+- compatible : Should be "hisilicon,hi655x-pmic-driver"
+- reg: Base address of PMIC on hi6220 soc
+- #interrupt-cells: Should be 2, is the local IRQ number for hi655x.
+- interrupt-controller: hi655x has internal IRQs (has own IRQ domain).
+- pmu_irq_gpio: should be &gpio_pmu_irq_n, is the IRQ gpio of hi655x.
+
+Example:
