- * camera image capture (abstract) bus driver
- *
- * Copyright (C) 2008, Guennadi Liakhovetski <kernel@pengutronix.de>
- *
- * This driver provides an interface between platform-specific camera
- * busses and camera devices. It should be used if the camera is
- * connected not over a "proper" bus like PCI or USB, but over a
- * special bus, like, for example, the Quick Capture interface on PXA270
- * SoCs. Later it should also be used for i.MX31 SoCs from Freescale.
- * It can handle multiple cameras and / or multiple busses, which can
- * be used, e.g., in stereo-vision applications.
- *
- * This program is free software; you can redistribute it and/or modify
- * it under the terms of the GNU General Public License version 2 as
