- 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>;
- };
