1* OMAP Interrupt Controller
2
3OMAP2/3 are using a TI interrupt controller that can support several
4configurable number of interrupts.
5
6Main node required properties:
7
8- compatible : should be:
9 "ti,omap2-intc"
10- interrupt-controller : Identifies the node as an interrupt controller
11- #interrupt-cells : Specifies the number of cells needed to encode an
12 interrupt source. The type shall be a <u32> and the value shall be 1.
13
14 The cell contains the interrupt number in the range [0-128].
15- ti,intc-size: Number of interrupts handled by the interrupt controller.
16- reg: physical base address and size of the intc registers map.
17
18Example:
19
20 intc: interrupt-controller@1 {
21 compatible = "ti,omap2-intc";
22 interrupt-controller;
23 #interrupt-cells = <1>;
24 ti,intc-size = <96>;
25 reg = <0x48200000 0x1000>;
26 };
