1Broadcom Generic Level 2 Interrupt Controller
2
3Required properties:
4
5- compatible: should be one of:
6	      "brcm,hif-spi-l2-intc" or
7	      "brcm,upg-aux-aon-l2-intc" or
8	      "brcm,l2-intc" for latched interrupt controllers
9              should be "brcm,bcm7271-l2-intc" for level interrupt controllers
10- reg: specifies the base physical address and size of the registers
11- interrupt-controller: identifies the node as an interrupt controller
12- #interrupt-cells: specifies the number of cells needed to encode an
13  interrupt source. Should be 1.
14- interrupts: specifies the interrupt line in the interrupt-parent irq space
15  to be used for cascading
16
17Optional properties:
18
19- brcm,irq-can-wake: If present, this means the L2 controller can be used as a
20  wakeup source for system suspend/resume.

22Example:
23
24hif_intr2_intc: interrupt-controller@f0441000 {
25	compatible = "brcm,l2-intc";
26	reg = <0xf0441000 0x30>;
27	interrupt-controller;
28	#interrupt-cells = <1>;
29	interrupt-parent = <&intc>;
30	interrupts = <0x0 0x20 0x0>;
31};
