1*4882a593Smuzhiyun* TI Common Platform Interrupt Controller
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunCommon Platform Interrupt Controller (cp_intc) is used on
4*4882a593SmuzhiyunOMAP-L1x SoCs and can support several configurable number
5*4882a593Smuzhiyunof interrupts.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunMain node required properties:
8*4882a593Smuzhiyun
9*4882a593Smuzhiyun- compatible : should be:
10*4882a593Smuzhiyun	"ti,cp-intc"
11*4882a593Smuzhiyun- interrupt-controller : Identifies the node as an interrupt controller
12*4882a593Smuzhiyun- #interrupt-cells : Specifies the number of cells needed to encode an
13*4882a593Smuzhiyun  interrupt source. The type shall be a <u32> and the value shall be 1.
14*4882a593Smuzhiyun
15*4882a593Smuzhiyun  The cell contains the interrupt number in the range [0-128].
16*4882a593Smuzhiyun- ti,intc-size: Number of interrupts handled by the interrupt controller.
17*4882a593Smuzhiyun- reg: physical base address and size of the intc registers map.
18*4882a593Smuzhiyun
19*4882a593SmuzhiyunExample:
20*4882a593Smuzhiyun
21*4882a593Smuzhiyun	intc: interrupt-controller@1 {
22*4882a593Smuzhiyun		compatible = "ti,cp-intc";
23*4882a593Smuzhiyun		interrupt-controller;
24*4882a593Smuzhiyun		#interrupt-cells = <1>;
25*4882a593Smuzhiyun		ti,intc-size = <101>;
26*4882a593Smuzhiyun		reg = <0xfffee000 0x2000>;
27*4882a593Smuzhiyun	};
