* 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:
- maxim,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:

Device Supply Names Description
------ ------------ -----------
max8925-onkey : : On key
max8925-rtc : : RTC
max8925-regulator : : Regulators
max8925-backlight : : Backlight
max8925-touch : : Touchscreen
max8925-power : : Charger

Example:

pmic: max8925@3c {
compatible = "maxim,max8925";
reg = <0x3c>;
interrupts = <1>;
interrupt-parent = <&intcmux4>;
interrupt-controller;
#interrupt-cells = <1>;

max8925-battery bindings
~~~~~~~~~~~~~~~~

Optional properties :
- batt-detect: whether support battery detect
- topoff-threshold: set charging current in topoff mode
- fast-charge: set charging current in fast mode
- no-temp-support: whether support temperature protection detect
- no-insert-detect: whether support insert detect

Example:
charger {
batt-detect = <0>;
topoff-threshold = <1>;
fast-charge = <7>;
no-temp-support = <0>;
no-insert-detect = <0>;
