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

20Example:
21
22hif_intr2_intc: interrupt-controller@f0441000 {
23 compatible = "brcm,l2-intc";
24 reg = <0xf0441000 0x30>;
25 interrupt-controller;
26 #interrupt-cells = <1>;
27 interrupt-parent = <&intc>;
28 interrupts = <0x0 0x20 0x0>;
29};
