| 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>; |
| }; |
