1*c66ec88fSEmmanuel Vadot* OMAP Interrupt Controller
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotOMAP2/3 are using a TI interrupt controller that can support several
4*c66ec88fSEmmanuel Vadotconfigurable number of interrupts.

6*c66ec88fSEmmanuel VadotMain node required properties:
7*c66ec88fSEmmanuel Vadot
8*c66ec88fSEmmanuel Vadot- compatible : should be:
9*c66ec88fSEmmanuel Vadot	"ti,omap2-intc"
10*c66ec88fSEmmanuel Vadot- interrupt-controller : Identifies the node as an interrupt controller
11*c66ec88fSEmmanuel Vadot- #interrupt-cells : Specifies the number of cells needed to encode an
12*c66ec88fSEmmanuel Vadot  interrupt source. The type shall be a <u32> and the value shall be 1.
13*c66ec88fSEmmanuel Vadot
14*c66ec88fSEmmanuel Vadot  The cell contains the interrupt number in the range [0-128].
15*c66ec88fSEmmanuel Vadot- ti,intc-size: Number of interrupts handled by the interrupt controller.
16*c66ec88fSEmmanuel Vadot- reg: physical base address and size of the intc registers map.
17*c66ec88fSEmmanuel Vadot
18*c66ec88fSEmmanuel VadotExample:
19*c66ec88fSEmmanuel Vadot
20*c66ec88fSEmmanuel Vadot	intc: interrupt-controller@1 {
21*c66ec88fSEmmanuel Vadot		compatible = "ti,omap2-intc";
22*c66ec88fSEmmanuel Vadot		interrupt-controller;
23*c66ec88fSEmmanuel Vadot		#interrupt-cells = <1>;
24*c66ec88fSEmmanuel Vadot		ti,intc-size = <96>;
25*c66ec88fSEmmanuel Vadot		reg = <0x48200000 0x1000>;
