+TB10x Top Level Interrupt Controller
+====================================
+
+The Abilis TB10x SOC contains a custom interrupt controller. It performs
+one-to-one mapping of external interrupt sources to CPU interrupts and
+provides support for reconfigurable trigger modes.
+
+Required properties
+-------------------
+
+- compatible: Should be "abilis,tb10x-ictl"
+- reg: specifies physical base address and size of register range.
+- interrupt-congroller: Identifies the node as an interrupt controller.
+- #interrupt cells: Specifies the number of cells used to encode an interrupt
+  source connected to this controller. The value shall be 2.
+- interrupt-parent: Specifies the parent interrupt controller.
+- interrupts: Specifies the list of interrupt lines which are handled by
+  the interrupt controller in the parent controller's notation. Interrupts
+  are mapped one-to-one to parent interrupts.
+
+Example
+-------
+
+intc: interrupt-controller {   /* Parent interrupt controller */
+       interrupt-controller;
+       #interrupt-cells = <1>; /* For example below */
+       /* ... */
+};
+
+tb10x_ictl: pic@2000 {         /* TB10x interrupt controller */
+       compatible = "abilis,tb10x-ictl";
+       reg = <0x2000 0x20>;
+       interrupt-controller;
+       #interrupt-cells = <2>;
+       interrupt-parent = <&intc>;
+       interrupts = <5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
+                       20 21 22 23 24 25 26 27 28 29 30 31>;
+};
