TS-4800 FPGA interrupt controller
|
|
|
|
TS-4800 FPGA has an internal interrupt controller. When one of the
|
|
interrupts is triggered, the SoC is notified, usually using a GPIO as
|
|
parent interrupt source.
|
|
|
|
Required properties:
|
|
- compatible: should be "technologic,ts4800-irqc"
|
|
- interrupt-controller: identifies the node as an interrupt controller
|
|
- reg: physical base address of the controller and length of memory mapped
|
|
region
|
|
- #interrupt-cells: specifies the number of cells needed to encode an interrupt
|
|
source, should be 1.
|
|
- interrupt-parent: phandle to the parent interrupt controller this one is
|
|
cascaded from
|
|
- interrupts: specifies the interrupt line in the interrupt-parent controller
