| 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 |
