7title: VIA and WonderMedia SoCs Interrupt Controller
8
9description:
10  This is the interrupt controller used in single-core ARM SoCs made by
11  VIA and WonderMedia (up to and including WM8950). Each block handles
12  up to 64 interrupt sources (level or edge triggered) and can generate
13  up to 8 interrupts to its parent when used in a chained configuration.
