+* Maxim max8925 Power Management IC
+
+Required parent device properties:
+- compatible : "maxim,max8925"
+- reg : the I2C slave address for the max8925 chip
+- interrupts : IRQ line for the max8925 chip
+- interrupt-controller: describes the max8925 as an interrupt
+ controller (has its own domain)
+- #interrupt-cells : should be 1.
+ - The cell is the max8925 local IRQ number
+
+Optional parent device properties:
+- tsc-irq: there are 2 IRQ lines for max8925, one is indicated in
+ interrupts property, the other is indicated here.
+
+max8925 consists of a large and varied group of sub-devices:

+max8925-onkey : : On key
+max8925-rtc : : RTC
+max8925-regulator : : Regulators
+max8925-backlight : : Backlight
+max8925-touch : : Touchscreen
+max8925-power : : Charger
