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.
