[GIT PULL for 5.12] V4L2 camera sensor and other patches

[Sakari Ailus <sakari.ailus@iki.fi>]

Hi Mauro,

Here's a large chunk of V4L2 core IOCTL handling, documentation, camera
sensor and IPU3 patches for 5.12. Notable additions are drivers for ov5648
and ov8856 drivers from Paul Kocialkowski.

A few patches changing V4L2 core IOCTL handling address a long-standing
memory leak issue.

Documentation patches improve documentation e.g. on V4L2 sub-device ops,
add an entity function for ISPs and document clock handling for camera
sensors and document relation between pixel rate and link frequency on
CSI-2 with C-PHY.

There are also noteworthy improvements to the ov5647 driver from Jacopo
Mondi and Dave Stevenson.

Please pull.
