This patch series adds basic support for the media controller at the
DVB core: it creates one media entity per DVB devnode, if the media
device is passed as an argument to the DVB structures.
The cx231xx driver was modified to pass such argument for DVB NET,
DVB frontend and DVB demux.
-
version 2:
- Now the PADs are created for all nodes
- Instead of using entity->flags for subtypes, create separate
MEDIA_ENT_T_DEVNODE_DVB_foo for each DVB devtype
- The API change patch was split from the DVB core changes
TODO:
- Create links
- Update media API for the DVB media controller changes
- Add the new devnodes at media-ctl at v4l-utils
