+Amazon's Annapurna Labs Fabric Interrupt Controller
+
+Required properties:
+
+- compatible: should be "amazon,al-fic"
+- reg: physical base address and size of the registers
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: must be 2.
+- interrupt-parent: specifies the parent interrupt controller.
+- interrupts: describes which input line in the interrupt parent, this
+  fic's output is connected to.
+
+Example:
+
+amazon_fic: amazon_fic {
+	compatible = "amazon,al-fic";
+	interrupt-controller;
+	#interrupt-cells = <1>;
+	reg = <0x0 0xfd8a8500 0x0 0x1000>;
+	interrupt-parent = <&gic>;
+	interrupts = <GIC_SPI 0x0 IRQ_TYPE_LEVEL_HIGH>;
+};
