    +Broadcom Generic Level 2 Interrupt Controller
    +
    +Required properties:
    +
    +- compatible: should be "brcm,l2-intc"
    +- reg: specifies the base physical address and size of the registers
    +- interrupt-controller: identifies the node as an interrupt controller
    +- #interrupt-cells: specifies the number of cells needed to encode an
    + interrupt source. Should be 1.
    +- interrupt-parent: specifies the phandle to the parent interrupt controller
    + this controller is cacaded from
    +- interrupts: specifies the interrupt line in the interrupt-parent irq space
    + to be used for cascading
    +
    +Optional properties:
    +
    +- brcm,irq-can-wake: If present, this means the L2 controller can be used as a
    + wakeup source for system suspend/resume.
    +
    +Example:
    +
    +hif_intr2_intc: interrupt-controller@f0441000 {
    + compatible = "brcm,l2-intc";
    + reg = <0xf0441000 0x30>;
    + interrupt-controller;
    + #interrupt-cells = <1>;
    + interrupt-parent = <&intc>;
    + interrupts = <0x0 0x20 0x0>;
    +};
