Some WPF instances, on Gen3 devices, can perform 90° rotation when writing frames to memory. Implement support for this using the V4L2_CID_ROTATE control. Signed-off-by:

V4L2 exposes parameters that influence buffers sizes through the format ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT, VIDIOC_S_FMT, and possibly VIDIOC_G_SELECTION and VIDIOC_S_SELECTION). Other parameters not part of the format structure may also influence buffer sizes or buffer layout in general. One existing such parameter is rotation, which is implemented by the V4L2_CID_ROTATE control and thus exposed through the V4L2 control ioctls. The interaction between those parameters and buffers is currently only partially specified by the V4L2 API. In particular interactions between controls and buffers isn't specified at all. The behaviour of the VIDIOC_S_FMT and VIDIOC_S_SELECTION ioctls when buffers are allocated is also not fully specified. This patch clearly defines and documents the interactions between formats, selections, controls and buffers. The preparatory discussions for the documentation change considered completely disallowing controls that change the buffer size or layout, in favour of extending the format API with a new ioctl that would bundle those controls with format information. The idea has been rejected, as this would essentially be a restricted version of the upcoming request API that wouldn't bring any additional value. Another option we have considered was to mandate the use of the request API to modify controls that influence buffer size or layout. This has also been rejected on the grounds that requiring the request API to change rotation even when streaming is stopped would significantly complicate implementation of drivers and usage of the V4L2 API for applications. Applications will however be required to use the upcoming request API to change at runtime formats or controls that influence the buffer size or layout, because of the need to synchronize buffers with the formats and controls. Otherwise there would be no way to interpret the content of a buffer correctly. Signed-off-by:

'Reset' loop does not look correct. I tested it very many times and it never repeated those commands. If problem, it tries to solve, really occurs on some situations better solution should be find out. There is another patch which does not have such hackish looking loop. Lets change to it.

The XV601/709 encodings are special: they signal limited range, but use the full range to encode a larger gamut with R', G' and B' values outside the [0-1] range. So don't clamp to limited range for these two encodings. Signed-off-by:

To let userspace propagate formats downstream in a media controller scenario, the video source pad (now pad 1, DEMOD_PAD_VID_OUT) must allow setting and getting the format. Incidentally, tvp5150_fill_fmt was implemented for this pad, not for the new analog input pad (now pad 0, DEMOD_PAD_IF_INPUT).
