No commit text?

This patch needs to be squashed together with the patch that changes the
driver. There is no value in separating them.

+* Marvell 88pm80x Power Management IC
+
+Required parent device properties:
+- compatible : "marvell,88pm80x"
+- reg : the I2C slave address for the 88pm80x chip
+- interrupts : IRQ line for the 88pm80x chip
+- interrupt-controller: describes the 88pm80x as an interrupt controller (has its own domain)
+- #interrupt-cells : should be 1.
+ - The cell is the 88pm80x local IRQ number
+
+Optional parent device properties:
+- marvell,88pm80x-irqmode: inicates whether interrupt status is cleared by read
+- marvell,88pm80x-poweraddr: 88pm80x are multi-chips solution. <reg> stores the I2C address
+ of one chip, and this property stores the I2C address of
+ power related chip.
+- marvell,88pm80x-gpadcaddr: 88pm80x are multi-chips solution. <reg> stores the I2C address
+ of one chip, and this property stores the I2C address of
+ gpadc related chip.
If it is multichip, then I would expect either a separate node for each
chip and these properties use phandles (instead of i2c addresses) to
point to the other chip nodes.

Alternately, if the cluster is described using a single node, then you
can put all three i2c addresses into the 'reg' property.

combined to one patch. please help review again. Thanks!
