| 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 |
