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>;
};
