This patch adds new V4L2_CAP_VIDEO_M2M and V4L2_CAP_VIDEO_M2M_MPLANE capability flags that are intended to be used for memory-to-memory (M2M) devices, instead of ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT. V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT capability flags are left untouched and will be removed in future, after a transition period required for existing applications to be adapted to check only for V4L2_CAP_VIDEO_M2M.

Both V4L2 and V4L2 subdev interface have very similar selection APIs with differences foremost related to in-memory and media bus formats. However, the selection targets are the same for both. Most targets are and in the future will likely continue to be more the same than with any differences. Thus it makes sense to unify the documentation of the targets.

The string "_ACTUAL" does not say anything more about the target names. Drop it.

This patch drops the _ACTIVE part from the selection target names as a prerequisite to unify the selection target names across the subdev and regular video node API. The meaning of V4L2_SEL_TGT_*_ACTIVE and V4L2_SUBDEV_SEL_TGT_*_ACTUAL selection targets is logically the same. Different names add to confusion where both APIs are used in a single driver or an application. For some system configurations different names may lead to interoperability issues. For backwards compatibility V4L2_SEL_TGT_CROP_ACTIVE and V4L2_SEL_TGT_COMPOSE_ACTIVE are defined as aliases to V4L2_SEL_TGT_CROP and V4L2_SEL_TGT_COMPOSE. These aliases will be removed after deprecation period, according to Documentation/feature-removal-schedule.txt.

Fix the documentation of the Y4 and Y6 formats. Fix a poll() issue, add support for enum_frmsizes, set the proper parent device and fix a few compliance issues. Tested with an actual Connectix B&W parallel port webcam, both on a little-endian and a big-endian platform. This driver has never been so good, doing 320x240 at 1 frame per second :-) I know, nobody cares, but still it is cool that linux can still support this old webcam.

V4L2 uses the enum type in IOCTL arguments in IOCTLs that were defined until the use of enum was considered less than ideal. Recently Rémi Denis-Courmont brought up the issue by proposing a patch to convert the enums to unsigned: <URL:http://www.spinics.net/lists/linux-media/msg46167.html> This sparked a long discussion where another solution to the issue was proposed: two sets of IOCTL structures, one with __u32 and the other with enums, and conversion code between the two: <URL:http://www.spinics.net/lists/linux-media/msg47168.html> Both approaches implement a complete solution that resolves the problem. The first one is simple but requires assuming enums and __u32 are the same in size (so we won't break the ABI) while the second one is more complex and less clean but does not require making that assumption. The issue boils down to whether enums are fundamentally different from __u32 or not, and can the former be substituted by the latter. During the discussion it was concluded that the __u32 has the same size as enums on all archs Linux is supported: it has not been shown that replacing those enums in IOCTL arguments would break neither source or binary compatibility. If no such reason is found, just replacing the enums with __u32s is the way to go. This is what this patch does. This patch is slightly different from Remi's first RFC (link above): it uses __u32 instead of unsigned and also changes the arguments of VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY.
