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>;

};
