[PATCH v3 0/7] document types of hardware control for V4L2

[Mauro Carvalho Chehab]

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.

Mauro Carvalho Chehab (7):
  media: add glossary.rst with a glossary of terms used at V4L2 spec
  media: open.rst: better document device node naming
  media: open.rst: remove the minor number range
  media: open.rst: document devnode-centric and mc-centric types
  media: open.rst: Adjust some terms to match the glossary
  media: videodev2: add a flag for MC-centric devices
  media: open.rst: add a notice about subdev-API on vdev-centric

v3:

- Add a glossary to be used by the new documentation about hardware control;
- Add a patch removing minor number range
- Use glossary terms at open.rst
- Split the notice about subdev-API on vdev-centric, as this change
   will require further discussions.

v2:

- added a patch at the beginning of the series better defining the
  device node naming rules;
- better defined the differenes between device hardware and V4L2 device node
  as suggested by Laurent and with changes proposed by Hans and Sakari
- changed the caps flag to indicate MC-centric devices
- removed the final patch that would use the new caps flag. I'll write it
  once we agree on the new caps flag.
