| 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.
 | |
| - 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>;
 | |
| };
