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>;
};
