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 }; 27 28
