| 2 | |
| 3 | TS-4800 FPGA has an internal interrupt controller. When one of the |
| 4 | interrupts is triggered, the SoC is notified, usually using a GPIO as |
| 5 | parent interrupt source. |
| 6 | |
| 7 | Required properties: |
| 8 | - compatible: should be "technologic,ts4800-irqc" |
| 9 | - interrupt-controller: identifies the node as an interrupt controller |
| 10 | - reg: physical base address of the controller and length of memory mapped |
| 11 | region |
| 12 | - #interrupt-cells: specifies the number of cells needed to encode an interrupt |
| 13 | source, should be 1. |
| 14 | - interrupt-parent: phandle to the parent interrupt controller this one is |
| 15 | cascaded from |
| 16 | - interrupts: specifies the interrupt line in the interrupt-parent controller |
