Kernel-3.10.0-957.el7_max8925

• 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:
