Hi Mauro,

This set contains support for multiple streams over a single MC link, a set
that has been out of tree for more than five years, has worked on by more
than five people in their turns. I think it is now ready for upstream.

Source sub-devices with multiple streams aren't supported yet but the
intent is to add the support soon.

Using the new APII requires setting v4l2_subdev_enable_streams_api in
drivers/media/v4l2-core/v4l2-subdev.c to true, so no new API is exposed to
the user space quite yet. The intent is also to change this soon, possibly
for 6.3 but may well slip to 6.4.

since v1:

- Fix documentation build and compile warnings.

Please pull.
