V4L/DVB (8610): Add suspend/resume capabilities to soc_camera.

2008-08-06T09:57:32+00:00

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.

V4L/DVB (8339): soc_camera: Add 16-bit bus width support

2008-07-20T10:25:26+00:00

The SuperH Mobile CEU hardware supports 16-bit width bus,
so extend the soc_camera code with SOCAM_DATAWIDTH_16.

V4L/DVB (8338): soc_camera: Move spinlocks

2008-07-20T10:25:21+00:00

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.

V4L/DVB (8337): soc_camera: make videobuf independent

2008-07-20T10:25:17+00:00

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.

V4L/DVB (7501): soc-camera: use a spinlock for videobuffer queue

2008-04-24T17:07:57+00:00

All drivers should provide a spinlock to be used in videobuf operations.

V4L/DVB (7500): soc-camera: extract function pointers from host object into operations

2008-04-24T17:07:57+00:00

Function pointers and the driver owner are not expected to change
throughout soc-camera host's life. Extract them into an operations struct.

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.

V4L/DVB (7276): soc-camera: deactivate cameras when not used

2008-04-24T17:07:46+00:00

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.

V4L/DVB (7170): soc_camera V4L2 driver for directly-connected SoC-based cameras

2008-04-24T17:07:42+00:00

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.
