[PATCH 0/3] document types of hardware control for V4L2

[Mauro Carvalho Chehab <mchehab@s-opensource.com>]

On 2010, we introduced a new way to control complex V4L2 devices used
on embedded systems, but this was never documented, nor it is possible
for an userspace applicatin to detect the kind of control a device supports.

This series fill the gap.
