+* Marvell 88PM8xx Power Management IC
+
+Required parent device properties:
+- compatible : "marvell,88pm800", "marvell,88pm805", "marvell,88pm860"
+- reg : the I2C slave address for the 88pm8xx chip
+- interrupts : IRQ line for the 88pm8xx chip
+- interrupt-controller: describes the 88pm8xx as an interrupt controller
+- #interrupt-cells : should be 1.
+               - The cell is the 88pm8xx local IRQ number
+
+Optional parent device properties:
+- marvell,irq-clr-on-write: indicates whether interrupt status is cleared
+  by write or read.
+  If enabled, interrupt is cleared by write else just read would do.
+
+88pm8xx family of devices consists of varied group of sub-devices:
+
+Device                 Supply Names     Description
+------                 ------------     -----------
+88pm80x-onkey          :               : On key
+88pm80x-rtc            :               : RTC
+88pm80x-regulator      :               : Regulators
+
+Note: More device list will follow
