-* 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 {
-	compatible = "cortina,gemini-power-controller";
-	reg = <0x4b000000 0x100>;
-	interrupts = <26 IRQ_TYPE_EDGE_FALLING>;
-};
