dt-bindings: mfd: max8925: Convert to DT schema format
Convert the binding to DT schema format. The sub-functions of this MFD device do not have their own compatible string and are thus described directly in the MFD binding document after being converted to YAML.

* 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:
|
||||
|
||||
