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};
