2009-12-16V4L/DVB (13659): soc-camera: convert to the new mediabus APIGuennadi Liakhovetski
Convert soc-camera core and all soc-camera drivers to the new mediabus API. This also takes soc-camera client drivers one step closer to also be usable with generic v4l2-subdev host drivers.

(S_CROP) 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.

2009-09-19V4L/DVB (12510): soc-camera: (partially) convert to v4l2-(sub)dev APIGuennadi Liakhovetski
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.

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.

2009-06-16V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_linkGuennadi Liakhovetski
Currently pcm990 camera bus-width management functions request a GPIO and never free it again. With this approach the GPIO extender driver cannot be unloaded once camera drivers have been loaded, also unloading theb i2c-pxa bus driver produces errors, because the GPIO extender driver cannot unregister properly. Another problem is, that if camera drivers are once loaded before the GPIO extender driver, the platform code marks the GPIO unavailable and only a reboot helps to recover. Adding an explicit free_bus method and using it in mt9m001 and mt9v022 drivers fixes these problems.

MT9M001 datasheet says, that the data is ready on the falling edge of the pixel clock, but the driver wrongly sets the SOCAM_PCLK_SAMPLE_RISING flag.

instead of ID. 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.
