There are one enum and 4 functions undocumented there.
Document them. That will fix the broken links at the
v4l2-subdev.rst file.Signed-off-by: Mauro Carvalho Chehab

The Async API is actually part of the v4l2 subdev.
Move its declarations to it.Signed-off-by: Mauro Carvalho Chehab
-
Enrich the subdevice description by linking it to the
functions and structs from v4l2-subdev.h.Signed-off-by: Mauro Carvalho Chehab
-
This header were poorly documented, and weren't using the
kernel-doc format. Document everything but the macros using
the right format.While here, also fix the other comments to match the
Linux CodingStyle.Signed-off-by: Mauro Carvalho Chehab

There are lots of documentation about V4L2 subdevices at
v4l2-framework.rst. Move them to its specific chapter at
v4l2-subdev.rst.Signed-off-by: Mauro Carvalho Chehab
-
This document describes the main kAPI interfaces for the
v4l2-device.h header. Add cross references to the documentation
produced via kernel-doc.While here, also use monotonic font for constants.

Part of the contents of v4l2-framework is related to the
kAPI defined by v4l2-device. Move such contents to the
v4l2-device.rst.Signed-off-by: Mauro Carvalho Chehab

Sphinx produce a 1:1 mapping between a rst file and an html file.
So, we need to split the kernel-doc tags on multiple documents.
A side effect is that we're now having a better name for each
section of the kAPI documentation.Signed-off-by: Mauro Carvalho Chehab
-
The functions at v4l2-device.h are not using the proper
markups. Add it, and include at the v4l2-core.rst.Signed-off-by: Mauro Carvalho Chehab
-
The kAPI, v4l-drivers and dvb-drivers never used the
GNU FDL license. The addition of such license header were
just due to copy-and-paste. So, let's fix it.As the media_kapi were part of device-drivers.tmp, it is
under GPL v2+.The other two books is an agregation of files without any
license explicitly specified. So, they're all bound to the
Kernel's COPYING license. So, they're GPL v2 only.Signed-off-by: Mauro Carvalho Chehab
-
The Sphinx note markup for media_remove_intf_links() is wrong:
there's a missing space.While here, let's auto-numerate the two notes.

The uAPI book has 5 parts, but they lost numeration after
conversion to rst. Manually number those parts, and make
the main index with 1 depth, to only show the parts and
the annexes.At each part, use :maxwidth: 5, in order to show a more
complete index.While here, fix the cross-references between different
books.Signed-off-by: Mauro Carvalho Chehab

Fix all remaining media warnings with ReST that are fixable
without changing at the Sphinx code.Signed-off-by: Mauro Carvalho Chehab

This reverts commit 47d6d752b9e20dbe8a2acd22e887be81a6f39de9.
Commit f42ddca7bebc (doc-rst: kernel-doc directive, fix state machine
reporter) from Marcus Heiser provides a better fix, so this configuration
change is no longer needed. -
Add a reporter replacement that assigns the correct source name and line
number to a system message, as recorded in a ViewList.[1] http://mid.gmane.org/CAKMK7uFMQ2wOp99t-8v06Om78mi9OvRZWuQsFJD55QA20BB3iw@mail.gmail.com

Now that the new Sphinx world order is taking over, the information in
kernel-doc-nano-HOWTO.txt is outmoded. I hate to remove it altogether,
since it's one of those files that people expect to find. But we can add a
warning and fix all the other pointers to it.Reminded-by: Daniel Vetter

Unfortunately warnings generated after parsing in sphinx can end up
with entirely bogus files and line numbers as sources. Strangely for
outright errors this is not a problem. Trying to convert warnings to
errors also doesn't fix it.The only way to get useful output out of sphinx to be able to root
cause the error seems to be enabling keep_warnings, which inserts
a System Message into the actual output. Not pretty at all, but I
don't really want to fix up core rst/sphinx code, and this gets the job
done meanwhile.Cc: Markus Heiser

Update and expand the CEC documentation. Especially w.r.t. non-blocking
mode.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
Even when the adapter is configured for CEC 1.4, we still check and
use the CEC 2.0 parts of struct cec_log_addrs. Although these aren't
used in CEC messages, the information contained in them is still of
use in the CEC framework itself, so keep this information.Also zero the unused trailing features[] data and unused logical address
data so the contents isn't random data.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
For POLLOUT poll only checked if the adapter was configured, not
if there was room in the transmit queue. Add that check.Signed-off-by: Hans Verkuil

Just pass the transmitted CEC message to all CEC adapters.
This implements the Monitor All mode for vivid.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
The main message loop checks if the physical address was valid, and if
not it is assumed that the adapter had been unconfigured.However, this check is no longer correct, instead it should check
that both adap->is_configured and adap->is_configuring are false.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
The size of the transmit queue was unlimited, which meant that
in non-blocking mode you could flood the CEC adapter with messages
to be transmitted.Limit this to 18 messages.
Also print the number of pending transmits and the timeout value
in the status debugfs file.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
Ensure that the unused part of the msg array is zeroed. This is
required by CEC 2.0 when receiving shorter messages than expected.
In that case the remaining bytes are assumed to be 0.There are no such CEC messages yet, but it is required to be future proof.
And since we're doing it for received messages, do it for transmitted
messages as well. It's unambiguous this way.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
The filehandle was set to NULL when in non-blocking mode or when
no reply is needed.This is wrong: the filehandle is needed in non-blocking mode to ensure
that the result of the transmit can be obtained through CEC_RECEIVE.And the 'reply' check was also incorrect since it should have checked the
timeout field (the reply can be 0). In any case, when in blocking mode
there is no need to set the fh to NULL either.Signed-off-by: Hans Verkuil
Signed-off-by: Mauro Carvalho Chehab -
Before transmitting a message clear all status fields and always fill
in the sequence number. Make sure the sequence number is never 0.Signed-off-by: Hans Verkuil

When CEC_RECEIVE returns a message the original timeout field
was overwritten. Restore the timeout field.Signed-off-by: Hans Verkuil

Sphinx is really evil when an older version finds an extra
attribute for the :toctree: tag: it simply ignores everything
and produce documents without any chapter inside!As we're now using tags available only on Sphinx 1.4.x, we
need to use some creative ways to add a title before the
table of contents. Do that by using a css class.Signed-off-by: Mauro Carvalho Chehab

The titles at the media books were misleading, and some books
were not numbered.Rename the kAPI book to better reflect its contents, be more
consistent on the initial rst file for each book and better
name them.Signed-off-by: Mauro Carvalho Chehab

I ended by adding twice each media header, because I saw some
missing stuff at the documents. It seems it was my mistake,
as everything seems to be there.So, remove those extra stuff, to avoid duplicating the
