title: VIA and WonderMedia SoCs Interrupt Controller
description:
This is the interrupt controller used in single-core ARM SoCs made by
VIA and WonderMedia (up to and including WM8950). Each block handles
up to 64 interrupt sources (level or edge triggered) and can generate
up to 8 interrupts to its parent when used in a chained configuration.
