2008-08-06V4L/DVB (8610): Add suspend/resume capabilities to soc_camera.Robert Jarzmik
Add suspend/resume hooks to call soc operation specific suspend and resume functions. This ensures the camera chip has been previously resumed, as well as the camera bus. These hooks in camera chip drivers should save/restore chip context between suspend and resume time.

2008-07-20V4L/DVB (8339): soc_camera: Add 16-bit bus width supportMagnus Damm
The SuperH Mobile CEU hardware supports 16-bit width bus, so extend the soc_camera code with SOCAM_DATAWIDTH_16. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-07-20V4L/DVB (8338): soc_camera: Move spinlocksMagnus Damm
This patch moves the spinlock handling from soc_camera.c to the actual camera host driver. The spinlock_alloc/free callbacks are replaced with code in init_videobuf(). So far all camera host drivers implement their own spinlock_alloc/free methods anyway, and videobuf_queue_core_init() BUGs on a NULL spinlock argument, so, new camera host drivers will not forget to provide a spinlock when initialising their videobuf queues.

2008-07-20V4L/DVB (8337): soc_camera: make videobuf independentPaulius Zaleckas
Makes SoC camera videobuf independent. Includes all necessary changes for PXA camera driver (currently the only driver using soc_camera in the mainline). These changes are important for the future soc_camera based drivers.

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.
