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>;
|
||
|
|
};
