Changelog:
v2 -> v3:
- Used generic node name "poweroff" instead of "gemini-poweroff".
v1 -> v2:
- Renamed the node from "power-controller" to "gemini-poweroff" to resolve dtschema warnings.

-* Device-Tree bindings for Cortina Systems Gemini Poweroff
-
-This is a special IP block in the Cortina Gemini SoC that only
-deals with different ways to power the system down.
-
-Required properties:
-- compatible: should be "cortina,gemini-power-controller"
-- reg: should contain the physical memory base and size
-- interrupts: should contain the power management interrupt

-Example:
-
-power-controller@4b000000 {
