1 | TB10x Top Level Interrupt Controller |
2 | ==================================== | |
3 | ||
4 | The Abilis TB10x SOC contains a custom interrupt controller. It performs | |
5 | one-to-one mapping of external interrupt sources to CPU interrupts and | |
6 | provides support for reconfigurable trigger modes. | |
7 | ||
8 | Required 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. | |
20 | ||
21 | Example | |
22 | ------- | |
23 | ||
24 | intc: interrupt-controller { /* Parent interrupt controller */ | |
25 | interrupt-controller; | |
26 | #interrupt-cells = <1>; /* For example below */ | |
27 | /* ... */ | |
28 | }; | |
29 | ||
30 | tb10x_ictl: pic@2000 { /* TB10x interrupt controller */ | |
31 | compatible = "abilis,tb10x-ictl"; | |
32 | reg = <0x2000 0x20>; | |
33 | interrupt-controller; | |
34 | #interrupt-cells = <2>; | |
35 | interrupt-parent = <&intc>; | |
36 | interrupts = <5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | |
37 | 20 21 22 23 24 25 26 27 28 29 30 31>; | |
38 | }; |
