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

19Example:
20
21hif_intr2_intc: interrupt-controller@f0441000 {
22 compatible = "brcm,l2-intc";
23 reg = <0xf0441000 0x30>;
24 interrupt-controller;
25 #interrupt-cells = <1>;
26 interrupt-parent = <&intc>;
27 interrupts = <0x0 0x20 0x0>;
28};
