[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.

[media] dvbdev: document most of the functions/data structs

2015-08-22T22:39:38+00:00

Document the most relevant functions and data structs for developers that are working with the DVB subsystem. Signed-off-by: Mauro Carvalho Chehab Acked-by: Jonathan Corbet

[media] use a function for DVB media controller register

2015-03-02T14:29:39+00:00

This is really a simple function, but using it avoids to have if's inside the drivers. Also, the kABI becomes a little more clearer. This shouldn't generate any overhead, and the type check will happen when compiling with MC DVB enabled. So, let's do it. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: use adapter arg for dvb_create_media_graph()

2015-03-02T14:25:38+00:00

Instead of using media_dev argument for dvb_create_media_graph(), use the adapter. That allows to create a stub for this function, if compiled without DVB support, avoiding to add extra if's at the drivers. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: add a function to create DVB media graph

2015-02-13T23:10:15+00:00

We need to create a DVB graph, linking the several DVB devnodes. Add such function. Please notice that this helper function doesn't take into account devices with multiple DVB adapters and frontends. For devices with multiple adapters, they should either create two different media controller instances or to improve this function to take the adapter ID into account.

[media] dvbdev: add pad for the DVB devnodes

2015-02-13T23:10:14+00:00

We want to represent the links between the several DVB devnodes, so let's create PADs for them. The DVB net devnode is a different matter, as it is not related to the media stream, but with network. So, at least for now, let's not add any pad for it. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: add support for media controller

2015-02-13T23:10:12+00:00

Provide a way to register media controller device nodes at the DVB core. Please notice that the dvbdev callers also require changes for the devices to be registered via the media controller. Signed-off-by: Mauro Carvalho Chehab

[media] dvbdev: add a dvb_detach() macro

2014-06-17T15:04:47+00:00

The dvb_attach() was unbalanced, as there was no dvb_dettach. Ok, on current cases, the dettach is done by dvbdev, but that are some future corner cases where we may need to do this before registering the frontend. So, add a dvb_detach() and use it at dvb_frontend.c. Signed-off-by: Mauro Carvalho Chehab

[media] dvb: move the dvb core one level up

2012-08-14T02:08:14+00:00

just like the V4L2 core, move the DVB core to drivers/media, as the intention is to get rid of both "video" and "dvb" directories. Signed-off-by: Mauro Carvalho Chehab
