2009-08-25soc-camera: remove .gain and .exposure struct soc_camera_device membersGuennadi Liakhovetski
From: Guennadi Liakhovetski <g.liakhovetski@gmx.de> This makes the soc-camera interface for V4L2 subdevices thinner yet. Handle gain and exposure internally in each driver just like all other controls.

2009-08-25soc-camera: V4L2 API compliant scaling (S_FMT) and cropping (S_CROP)Guennadi Liakhovetski
From: Guennadi Liakhovetski <g.liakhovetski@gmx.de> The initial soc-camera scaling and cropping implementation turned out to be incompliant with the V4L2 API, e.g., it expected the user to specify cropping in output window pixels, instead of input window pixels. This patch converts the soc-camera core and all drivers to comply with the standard. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Priority: low

2009-08-25soc-camera: (partially) convert to v4l2-(sub)dev APIGuennadi Liakhovetski
From: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Convert the soc-camera framework to use the v4l2-(sub)dev API. Start using v4l2-subdev operations. Only a part of the interface between the soc_camera core, soc_camera host drivers on one side and soc_camera device drivers on the other side is replaced so far. The rest of the interface will be replaced in incremental steps, and will require extensions and, possibly, modifications to the v4l2-subdev code.

From: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Convert soc-camera core and all drivers to platform device API. We already converted platforms to register a platform device for each soc-camera client, now we remove the compatibility code and switch completely to the new scheme. This is a preparatory step for the v4l2-subdev conversion. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Priority: low

2008-12-30v4l2: debugging API changed to match against driver name instead of ID.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30.
