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 1
|
||
|
|
|
||
|
|
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 = <1>;
|
||
|
|
interrupt-parent = <&local_intc>;
|
||
|
|
};
