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.
