tristate "CPiA2 Video For Linux"
depends on VIDEO_DEV && USB
---help---
This is the video4linux driver for cameras based on Vision's CPiA2
(Colour Processor Interface ASIC), such as the Digital Blue QX5
Microscope. If you have one of these cameras, say Y here
This driver is also available as a module (cpia2).
