BCM2836 per-CPU interrupt controller
The BCM2836 has a per-cpu interrupt controller for the timer, PMU
events, and SMP IPIs. One of the CPUs may receive interrupts for the
peripheral (GPU) events, which chain to the BCM2835-style interrupt
controller.
Required properties:
- compatible: Should be "brcm,bcm2836-l1-intc"
- reg: Specifies 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. The value shall be 2
Please refer to interrupts.txt in this directory for details of the common
Interrupt Controllers bindings used by client devices.
The interrupt sources are as follows:
0: CNTPSIRQ
1: CNTPNSIRQ
2: CNTHPIRQ
3: CNTVIRQ
8: GPU_FAST
9: PMU_FAST
Example:
local_intc: local_intc {
compatible = "brcm,bcm2836-l1-intc";
reg = <0x40000000 0x100>;
interrupt-controller;
#interrupt-cells = <2>;
interrupt-parent = <&local_intc>;
};
