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