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

I gave a list of possible names, yet you chosen different one. No, it
does not work like that.

Please read the feedback and choose one of the names mentioned there.

And next time please read DT maintainer review feedback more carefully.

Best regards,
