2008-04-24V4L/DVB (7501): soc-camera: use a spinlock for videobuffer queueGuennadi Liakhovetski
All drivers should provide a spinlock to be used in videobuf operations. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Reviewed-by: Brandon Philips <bphilips@suse.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-04-24V4L/DVB (7336): soc-camera: streamline hardware parameter negotiationGuennadi Liakhovetski
Improve hardware parameter negotiation between the camera host driver and camera drivers. Parameters like horizontal and vertical synchronisation, pixel clock polarity shall be set depending on capabilities of the parties.

2008-04-24V4L/DVB (7276): soc-camera: deactivate cameras when not usedGuennadi Liakhovetski
Only attach cameras to the host interface for probing, then detach until open. This allows platforms with several cameras on an interface, physically supporting only one camera, to handle multiple cameras and activate them selectively after initial probing. The first attach during probe is needed to activate the host interface to be able to physically communicate with cameras.

2008-04-24V4L/DVB (7170): soc_camera V4L2 driver for directly-connected SoC-based camerasGuennadi Liakhovetski
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.
