    1 * Maxim max8925 Power Management IC
    2 
    3 Required parent device properties:
    4 - compatible : "maxim,max8925"
    5 - reg : the I2C slave address for the max8925 chip
    6 - interrupts : IRQ line for the max8925 chip
    7 - interrupt-controller: describes the max8925 as an interrupt
    8   controller (has its own domain)
    9 - #interrupt-cells : should be 1.
   10         - The cell is the max8925 local IRQ number
   11 
   12 Optional parent device properties:
   13 - maxim,tsc-irq: there are 2 IRQ lines for max8925, one is indicated in
   14   interrupts property, the other is indicated here.
   15 
   16 max8925 consists of a large and varied group of sub-devices:
