1*4882a593Smuzhiyun* OMAP Interrupt Controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunOMAP2/3 are using a TI interrupt controller that can support several
4*4882a593Smuzhiyunconfigurable number of interrupts.

6*4882a593SmuzhiyunMain node required properties:
7*4882a593Smuzhiyun
8*4882a593Smuzhiyun- compatible : should be:
9*4882a593Smuzhiyun	"ti,omap2-intc"
10*4882a593Smuzhiyun- interrupt-controller : Identifies the node as an interrupt controller
11*4882a593Smuzhiyun- #interrupt-cells : Specifies the number of cells needed to encode an
12*4882a593Smuzhiyun  interrupt source. The type shall be a <u32> and the value shall be 1.
13*4882a593Smuzhiyun
14*4882a593Smuzhiyun  The cell contains the interrupt number in the range [0-128].
15*4882a593Smuzhiyun- ti,intc-size: Number of interrupts handled by the interrupt controller.
16*4882a593Smuzhiyun- reg: physical base address and size of the intc registers map.
17*4882a593Smuzhiyun
18*4882a593SmuzhiyunExample:
19*4882a593Smuzhiyun
20*4882a593Smuzhiyun	intc: interrupt-controller@1 {
21*4882a593Smuzhiyun		compatible = "ti,omap2-intc";
22*4882a593Smuzhiyun		interrupt-controller;
23*4882a593Smuzhiyun		#interrupt-cells = <1>;
24*4882a593Smuzhiyun		ti,intc-size = <96>;
25*4882a593Smuzhiyun		reg = <0x48200000 0x1000>;
