Forgot to mention: 

This series, together with the part1 one is on this tree:
	https://git.linuxtv.org/mchehab/experimental.git/log/?h=v4l-docs-part2-v1

As I may not have time to address the remaining kAPI bits for
a while, let me document what kAPIs at include/media main dir
are still out of sync:

	- cec-pin.h: struct cec_pin;
	- cec.h: several structs;
	- media-device.h, media-devnode.h: a couple of defines;
	- rc-core.h: ancillary functions;
	- soc-camera.h, v4l2-clk.h, videobuf-*.h - probably not
	  worth the efforts, as those are obsolete kAPI;
	- v4l2-common.h: print macros. IMHO, we should try to get
	  rid of them, and use dev_foo() everywhere;
	- v4l2-fwnode.h: In this specific case, Sakari has a patch
	  series addressing it, moving existing documentation from
	  v4l2-fwnode.c;
	- v4l2-mem2mem.h: v4l2 ioctl helpers aren't documented;
	- videobuf2-*.h: This series contain several documentation
	  improvements there for VB2 core and V4L2, with are the
	  most important ones - as they're used by the drivers.
	  The other headers are either undocumented or barely
	  documented.

PS.: It should be noticed that there are other files under
     include/media and inside their sub-directories that aren't
     part of the media kAPI, but are driver-specific stuff,
     like, for example, imx.h, vsp1.h and i2c/ subdir.
