0001 * Maxim max8925 Power Management IC
0002
0003 Required parent device properties:
0004 - compatible : "maxim,max8925"
0005 - reg : the I2C slave address for the max8925 chip
0006 - interrupts : IRQ line for the max8925 chip
0007 - interrupt-controller: describes the max8925 as an interrupt
0008 controller (has its own domain)
0009 - #interrupt-cells : should be 1.
0010 - The cell is the max8925 local IRQ number
0011
0012 Optional parent device properties:
0013 - maxim,tsc-irq: there are 2 IRQ lines for max8925, one is indicated in
0014 interrupts property, the other is indicated here.
0015
0016 max8925 consists of a large and varied group of sub-devices:
