+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.
+ First cell defines the index of the interrupt within the controller.
+ Second cell is used to specify the trigger type and must be one of the
+ following:
+ - bits[3:0] trigger type and level flags
+ 1 = low-to-high edge triggered
+ 4 = active high level-sensitive
+- interrupt-parent: specifies the parent interrupt controller.
+- interrupts: describes which input line in the interrupt parent, this
+ fic's output is connected to. This field property depends on the parent's
+ binding
+
+Example:
+
+amazon_fic: interrupt-controller@0xfd8a8500 {
+ compatible = "amazon,al-fic";
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ reg = <0x0 0xfd8a8500 0x0 0x1000>;
+ interrupt-parent = <&gic>;
+ interrupts = <GIC_SPI 0x0 IRQ_TYPE_LEVEL_HIGH>;
+};
