| 8 | |
| 9 | description: |
| 10 | Interrupt controller and router for Realtek MIPS SoCs, allowing each SoC |
| 11 | interrupt to be routed to one parent CPU (hardware) interrupt, or left |
| 12 | disconnected. |
| 13 | All connected input lines from SoC peripherals can be masked individually, |
| 14 | and an interrupt status register is present to indicate which interrupts are |
| 15 | pending. |
