2016-08-23[media] docs-rst: Convert CEC uAPI to use C function referencesMauro Carvalho Chehab10-36/+47
Name all ioctl references and make them match the ioctls that are documented. That will improve the cross-reference index, as it will have all ioctls and syscalls there. While here, improve the documentation to make them to look more like the rest of the document. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-23[media] docs-next: stop abusing on the cpp domainMauro Carvalho Chehab9-9/+9
Now that we have an override for the c domain that will do the right thing for the Kernel, stop abusing on the cpp domain. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-08-23doc-rst: migrate ioctl CEC_DQEVENT to c-domainMarkus Heiser2-3/+4
This is only one example, demonstrating the benefits of the patch series. The CEC_DQEVENT ioctl is migrated to the sphinx c-domain and referred by ":name: CEC_DQEVENT". With this change the indirection using ":ref:`CEC_DQEVENT` is no longer needed, we can refer the ioctl directly with ":c:func:`CEC_DQEVENT`". As addition in the index, there is a entry "CEC_DQEVENT (C function)". Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2016-08-22[media] cec-ioc-receive.rst: one table here should be longtableMauro Carvalho Chehab1-0/+2
The table is too big to fit into a single page on LaTeX format. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-22[media] docs-rst: fix warnings introduced by LaTeX patchsetMauro Carvalho Chehab5-36/+21
Sphinx is really pedantic with respect to the order where table tags and references are created. Putting things at the wrong order causes troubles. The order that seems to work is: .. raw:: latex .. tabularcolumns:: .. _foo_name: .. cssclass: longtable .. flat-table:: Reorder the tags to the above order, to avoid troubles, and fix remaining warnings introduced by media recent patches.

2016-08-22[media] uapi/cec: adjust tables on LaTeX outputMauro Carvalho Chehab5-24/+21
Fix tables to avoid text to overflow the cell limits. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-22[media] docs-rst: add tabularcolumns to all tablesMauro Carvalho Chehab5-0/+36
LaTeX doesn't handle too well auto-width on tables, and ReST markup requires an special tag to give it the needed hints. As we're using A4 paper, we have 17cm of useful spaces. As most media tables have widths, let's use it to generate the needed via the following perl script: my ($line_size, $table_header, $has_cols) = (17.5, 0, 0); my $out; my $header = ""; my @widths = (); sub round { $_[0] > 0 ? int($_[0] + .5) : -int(-$_[0] + .5) } while (<>) { if (!$table_header) { $has_cols = 1 if (m/..\s+tabularcolumns::/); if (m/..\s+flat-table::/) { $table_header = 1; $header = $_; next; } $out .= $_; next; } $header .= $_; @widths = split(/ /, $1) if (m/:widths:\s+(.*)/); if (m/^\n$/) { if (!$has_cols && @widths) { my ($tot, $t, $i) = (0, 0, 0); foreach my $v(@widths) { $tot += $v; }; $out .= ".. tabularcolumns:: |"; for ($i = 0; $i < scalar @widths - 1; $i++) { my $v = $widths[$i]; my $w = round(10 * ($v * $line_size) / $tot) / 10; $out .= sprintf "p{%.1fcm}|", $w; $t += $w; } my $w = $line_size - $t; $out .= sprintf "p{%.1fcm}|\n\n", $w; } $out .= $header; $table_header = 0; $has_cols = 0; $header = ""; @widths = (); } } print $out; Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-22[media] docs-rst: better use the .. note:: tagMauro Carvalho Chehab11-11/+33
Change multi-line note tags to be more symetric, e. g. not starting the text together witht the tag. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-23[media] doc-rst: better organize the media booksMauro Carvalho Chehab1-6/+8
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 <mchehab@s-opensource.com>
2016-07-19[media] doc-rst: cec: update documentationHans Verkuil6-58/+110
Update and expand the CEC documentation. Especially w.r.t. non-blocking mode. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-13[media] doc-rst: fix an undefined referenceMauro Carvalho Chehab1-3/+3

Lots of fixups relating to references. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-13Revert "[media] docs-rst: escape [] characters"Mauro Carvalho Chehab3-6/+6
This patch touches on places where it shouldn't: image files and code examples. Also, it doesn't fix all array occurrences. So, let's revert it. This reverts commit ffbab694ede33c294e5864a5e0bf4d1474446a71.
2016-07-13[media] doc-rst: update CEC_RECEIVEHans Verkuil1-25/+41
The timestamp field was split into rx_ts and tx_ts, and the rx/tx_status fields were moved. Update the doc accordingly. Also fix a bug that stated that a non-zero tx_status field signaled an error. That's not true, since TX_STATUS_OK is 1, not 0. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-12[media] docs-rst: escape [] charactersMauro Carvalho Chehab3-6/+6
Those characters are used for citations. Better to escape, to avoid them to be misinterpreted. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-10[media] doc-rst: improve display of notes and warningsMauro Carvalho Chehab11-207/+207
There are several notes and warning mesages in the middle of the media docbook. Use the ReST tags for that, as it makes them visually better and hightlights them. While here, modify a few ones to make them clearer. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-10[media] doc-rst: remove an extra label on V4L2 and CEC partsMauro Carvalho Chehab1-1/+0
There's no need to say: Table of Contents there. Also, this generates a duplicated caption xref. So, remove, to use the same format on every part. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-09[media] doc-rst: make CEC look more like other parts of the bookMauro Carvalho Chehab3-55/+57
Better organize the contents of the CEC part, moving the introduction to chapter 1, placing all ioctls at chapter 2 and numerating all chapters and items. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-09[media] doc-rst: add CEC header file to the documentationMauro Carvalho Chehab7-85/+96
Adding the header file is interesting for several reasons: 1) It makes MC documentation consistend with other parts; 2) The header file can be used as a quick index to all API elements; 3) The cross-reference check helps to identify symbols that aren't documented. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-09[media] doc-rst: reformat cec-api.rstMauro Carvalho Chehab1-4/+10
