+* Faraday Technologt FTINTC010 interrupt controller
+
+This interrupt controller is a stock IP block from Faraday Technology found
+in the Gemini SoCs and other designs.
+
+Required properties:
+- compatible: must be one of
+  "faraday,ftintc010"
+  "cortina,gemini-interrupt-controller" (deprecated)
+- reg: The register bank for the interrupt controller.
+- interrupt-controller: Identifies the node as an interrupt controller
+- #interrupt-cells: The number of cells to define the interrupts.
+  Must be 2 as the controller can specify level or rising edge
+  IRQs. The bindings follows the standard binding for controllers
+  with two cells specified in
+  interrupt-controller/interrupts.txt
+
+Example:
+
+interrupt-controller@48000000 {
+	compatible = "faraday,ftintc010"
+	reg = <0x48000000 0x1000>;
+	interrupt-controller;
+	#interrupt-cells = <2>;
+};
