7title: Realtek RTL SoC interrupt controller
8
9description:
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.
