* OMAP Interrupt Controller
OMAP2/3 are using a TI interrupt controller that can support several
configurable number of interrupts.
Main node required properties:
- compatible : should be:
"ti,omap2-intc"
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
interrupt source. The type shall be a <u32> and the value shall be 1.
The cell contains the interrupt number in the range [0-128].
- ti,intc-size: Number of interrupts handled by the interrupt controller.
- reg: physical base address and size of the intc registers map.
Example:
intc: interrupt-controller@1 {
compatible = "ti,omap2-intc";
interrupt-controller;
#interrupt-cells = <1>;
ti,intc-size = <96>;
reg = <0x48200000 0x1000>;
};
