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 3:
- Added the second series of patches ("add link graph to cx231xx
using the media controller")
- tuner-core and cx25840: add proper error handling as suggested by
Sakari Ailus and pointed by Joe Perches;
- dvb core: move the media_dev struct to be inside the DVB adapter. That
allowed to simplify the changes for the dvbdev clients;
- Add logic to setup the pipelines when analog or digital TV stream starts.
- Renamed some patches to better describe its contents.
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:
- Update media API docbook for the DVB media controller changes
- Solve the issues pointed by a separate e-mail
Those patches are also available at my experimental tree:
