V4L2 API mandates, that drivers do not update the argument of the S_CROP ioctl() with the actual geometry. Comply. Signed-off-by:

Not all video capture devices can configure arbitrary cropping, whereas the CEU module on SuperH CPUs can crop with pixel precision. However, we want to use camera cropping if possible to save bandwidth and increase the frame-rate. This patch verifies whether the camera managed to crop exactly the requested rectangle, and if not, uses host-side cropping. To be able to crop on CEU we have to preserve camera rectangle too, for which the host_priv member in struct soc_camera_device is used. We now allocate memory dynamically, thus we have to use the .put_formats() method from struct soc_camera_host_ops to free it. Signed-off-by:

Patch [PATCH] video: use videobuf_waiton() in sh_mobile_ceu free_buffer() was not quite correct. It closed a race, but introduced a potential lock-up, if for some reason an interrupt does not come. This has been observed in tests with tw9910. This patch safely dequeues buffers without waiting for their completion. It also moves a buffer state assignment under a spinlock to make it atomic with queuing of the buffer. Signed-off-by:

The move of format translation initialisation into soc_camera_open() was temporary for the soc-camera as platform driver intermediate step, put it back into soc_camera_probe(). Also add a .put_formats() method to soc_camera_host_ops to free any resources host driver might have allocated in .get_formats(). Signed-off-by:

V4L2 drivers are allowed to configure a geometry different than what has been requested by the user with S_CROP, but then they have to adjust the input rectangle accordingly. Fix ov772x to comply with this requirement. Signed-off-by:

1. soc-camera always requests a valid rectangle, when calling .s_fmt(), no need to check and adjust 2. in .s_crop(), if the rectangle exceeds sensor limits, push it to the respective border instead of centering 3. take into account left and top borders when checking Signed-off-by:

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. Signed-off-by:

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:

This the vpfe capture bridge driver for doing video capture on DM355 and DM6446 evms. The ccdc hw modules register with the driver and are used for configuring the CCD Controller for a specific decoder interface. The driver also registers the sub devices required for a specific evm. More than one sub devices can be registered. This allows driver to switch dynamically to capture video from any sub device that is registered. Currently only one sub device (tvp5146) is supported. But in future this driver is expected to do capture from sensor devices such as Micron's MT9T001, MT9T031 and MT9P031 etc. The driver currently supports MMAP based IO.
