Prepare to divide videobuf2
- Separate vb2 trace events from v4l2 trace event.
- Make wrapper functions that will move to v4l2-side.
- Make vb2_core_* functions that will remain in core-side.
- Add a callback function table for buffer operation which makes vb2-core
to be able to invoke a v4l2-side functions.
- Rename internal functions as vb2_*.Signed-off-by: Junghak Sung

MFC driver never delivered EOS event to apps feeding constantly its capture
buffer with fresh buffers. The patch fixes it by marking last buffers
returned by MFC with MFC_BUF_FLAG_EOS flag and firing EOS event on
de-queuing such buffers.Signed-off-by: Andrzej Hajda

In videobuf2 dma-sg memory types the prepare and finish ops, instead
of passing the number of entries in the original scatterlist as the
"nents" parameter to dma_sync_sg_for_device() and dma_sync_sg_for_cpu(),
the value returned by dma_map_sg() was used. Albeit this has been
suggested in comments of some implementations (which have since been
corrected), this is wrong.Fixes: d790b7eda953 ("vb2-dma-sg: move dma_(un)map_sg here")

Now that the Demux kABI is documented at device-drivers.xml,
remove it from the API docbook.Signed-off-by: Mauro Carvalho Chehab
-
There are several stuff at media's kdapi.xml that don't
belong there, as it documents the Kernel internal ABI, and
not the userspace API.Add the documentation here. The hole kdapi.xml will be
removed on a latter patch, after we finish documenting
what's there at the proper places.Signed-off-by: Mauro Carvalho Chehab
-
While we can't document #defines, documenting enums are
well supported by kernel-doc. So, convert the bitmap defines
into an enum.Signed-off-by: Mauro Carvalho Chehab
-
The usage of #define at the kABI is fine, but it doesn't
allow adding a proper description. As those defines deserve
a proper documentation, let's convert them into an enum and
document them at device-drivers DocBook.Signed-off-by: Mauro Carvalho Chehab

The dvb/kdapi.tmpl has already an extensive documentation about
this callback. Now that we've added function typedefs at kernel-doc,

A typedef function looks more likely a function and not a
normal typedef. Change the code to use the output_function_*,
in order to properly parse the function prototype parameters.Signed-off-by: Mauro Carvalho Chehab

The current typedef parser only works for non-function typedefs.
As we need to also document some function typedefs, add a
parser for it.Signed-off-by: Mauro Carvalho Chehab

drivers use it. The kdapi.xml contains provision for some other
frontend source types, but it is not in sync with the code.So, remove the unused types and sync both files.

This enum is not actually used anymore. The only value used from
the enum is DMX_OK, passed as a parameter on two callbacks.Yet, this value is not used anywhere. So, just remove it.

There are two callbacks still not documented:
.//drivers/media/dvb-core/demux.h:422: warning: No description found for parameter 'get_pes_pids'
.//drivers/media/dvb-core/demux.h:422: warning: No description found for parameter 'get_stc'The purpose of first one is clear. The second one is used only
on the obsolete av7110 driver, and its purpose is not clear,
as it just returns a 64-bit word from the firmware to userspace.Let's document get_pes_pids and mark get_stc as private, adding
a comment to not use it, while this is not documented.Signed-off-by: Mauro Carvalho Chehab

There are two DVB demux callbacks and ioctls that aren't documented
and aren't used at all by the DVB core or by any DVB driver upstream.Let's comment out the code for those two ioctls and remove on some

There are a few inconsistencies between the old documentation
that got imported into the header and the current status.Update them, and use the proper doc-nano nomenclature for
struct artuments "@", instead of foo().Signed-off-by: Mauro Carvalho Chehab
-
The DocBook/media/dvb/kdapi.xml contains the description of
the kABI for DVB. The problem is that, by being maintained
on a separate file and not being updated for years, it got
outdated. So, for example, some callback parameters were
changed, but the DocBook were still using the old stuff.As a first step to fix it, let's move the documentation of
struct dmx_demux into demux.h and fix the parameters used
there.For now, don't document any other field nor touch the
descriptions that got moved, letting this job to other
patches. That makes easier to review the patch.PS.: Please notice that an additional patch will be needed
in order to fix the return values (some uses non-existent
return codes) and to the functions and callbacks mentioned at
the descriptions.Signed-off-by: Mauro Carvalho Chehab

There are several CodingStyle violations at the DVB code. While
we won't be fixing them as a hole, let's fix at least the
headers, as we're touching on them already in order to properly
document them.No functional changes.

The tuner-types.h is part of the V4L2 core and should be
touched for every new tuner added. So, it deserves to be

Right now, "private:" tag should be lower-case, otherwise the
scripts/kernel-doc won't do the right thing.Also, no fields after "private:" should be documented. As we don't
want to strip the documentation, let's untag. This way, it will
be seen only at the file, and not at the DocBooks.Signed-off-by: Mauro Carvalho Chehab
