1BCM2836 per-CPU interrupt controller
2
3The BCM2836 has a per-cpu interrupt controller for the timer, PMU
4events, and SMP IPIs.  One of the CPUs may receive interrupts for the
5peripheral (GPU) events, which chain to the BCM2835-style interrupt
6controller.

8Required properties:
9
10- compatible:	 	Should be "brcm,bcm2836-l1-intc"
11- reg:			Specifies base physical address and size of the
12			  registers
13- interrupt-controller:	Identifies the node as an interrupt controller
14- #interrupt-cells:	Specifies the number of cells needed to encode an
15			  interrupt source. The value shall be 2

18Interrupt Controllers bindings used by client devices.

20The interrupt sources are as follows:
21
220: CNTPSIRQ
231: CNTPNSIRQ
242: CNTHPIRQ
253: CNTVIRQ
268: GPU_FAST
279: PMU_FAST

29Example:

31local_intc: local_intc {
32	compatible = "brcm,bcm2836-l1-intc";
33	reg = <0x40000000 0x100>;
34	interrupt-controller;
35	#interrupt-cells = <2>;
36	interrupt-parent = <&local_intc>;
37};
