Rewrite the textual description for the VIA/WonderMedia interrupt controller as YAML schema. The original textual version did not contain information about the usage of 'interrupts' to describe the connection of a chained controller to its parent, add it here. A chained controller can trigger up to 8 different interrupts (IRQ0~7) on its parent.

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.
