[media] mxl111sf: Add a tuner entity

2016-01-11T14:19:26+00:00

While mxl111sf may have multiple frontends, it has just one tuner. Reflect that on the media graph. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: create links on devices with multiple frontends

2016-01-11T14:19:26+00:00

Devices like mxl111sf-based WinTV Aero-m have multiple frontends, all linked on the same demod. Currently, the dvb_create_graph() function is not smart enough to create multiple links. Fix it. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: Add RF connector if needed

2016-01-11T14:19:25+00:00

Several pure digital TV devices have a frontend with the tuner integrated on it. Add the RF connector when dvb_create_media_graph() is called on such devices. Tested with siano and dvb_usb_mxl111sf drivers. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: Document the new MC-related fields

2016-01-11T14:19:10+00:00

The Media Controller next gen patchset added several new fields to be used with it. Document them. Signed-off-by: Mauro Carvalho Chehab

[media] dvb core: must check dvb_create_media_graph()

2016-01-11T14:18:59+00:00

If media controller is enabled and mdev is filled, it should ensure that the media graph will be properly initialized. Enforce that. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: returns error if graph object creation fails

2016-01-11T14:18:57+00:00

Right now, if something gets wrong at dvb_create_media_entity() or at dvb_create_media_graph(), the device will still be registered. Change the logic to properly handle it and free all media graph objects if something goes wrong at dvb_register_device(). Also, change the logic at dvb_create_media_graph() to return an error code if something goes wrong. It is up to the caller to implement the right logic and to call dvb_unregister_device() to unregister the already-created objects. While here, add a missing logic to unregister the created interfaces. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] dvb: modify core to implement interfaces/entities at MC new gen

2016-01-11T14:18:52+00:00

The Media Controller New Generation redefines the types for both interfaces and entities to be used on DVB. Make the needed changes at the DVB core for all interfaces, entities and data and interface links to appear in the graph. Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: add support for interfaces

2016-01-11T14:18:48+00:00

Now that the infrastruct for that is set, add support for interfaces. Please notice that we're missing two links: DVB FE intf -> tuner DVB demux intf -> dvr Those should be added latter, after having the entire graph set. With the current infrastructure, those should be added at dvb_create_media_graph(), but it would also require some extra core changes, to allow the function to enumerate the interfaces.

[media] dvbdev: Remove two cut-and-paste errors

2015-10-01T12:18:09+00:00

Those two came from dvb_register_adapter cut-and-paste: .//drivers/media/dvb-core/dvbdev.h:199: warning: Excess function parameter 'device' description in 'dvb_register_device' .//drivers/media/dvb-core/dvbdev.h:199: warning: Excess function parameter 'adapter_nums' description in 'dvb_register_device' Remove them.
