+* 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:
