  • 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 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>;
};
