1TB10x Top Level Interrupt Controller
2====================================
3
4The Abilis TB10x SOC contains a custom interrupt controller. It performs
5one-to-one mapping of external interrupt sources to CPU interrupts and
6provides support for reconfigurable trigger modes.

8Required properties
9-------------------
10
11- compatible: Should be "abilis,tb10x-ictl"
12- reg: specifies physical base address and size of register range.
13- interrupt-congroller: Identifies the node as an interrupt controller.
14- #interrupt cells: Specifies the number of cells used to encode an interrupt
15  source connected to this controller. The value shall be 2.
16- interrupt-parent: Specifies the parent interrupt controller.
17- interrupts: Specifies the list of interrupt lines which are handled by
18  the interrupt controller in the parent controller's notation. Interrupts
19  are mapped one-to-one to parent interrupts.
