2019-03-01media: Documentation: fix several typosMauro Carvalho Chehab1-1/+1
Use codespell to fix lots of typos over frontends. Manually verified to avoid false-positives. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> Acked-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-12-05media: add SPDX header to media uAPI filesMauro Carvalho Chehab1-0/+9
All those files are under GFDL 1.1 or later, with no invariant sections. Tag them as such. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-12-05media: remove text encoding from rst filesMauro Carvalho Chehab1-2/+0
This is not needed there. Also, the same UTF-8 encoding should be used on all documents. Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-11-23media: v4l: uAPI doc: Changing frame interval won't change formatSakari Ailus1-0/+3
Document that changing the frame interval has no effect on frame size. While this was the assumption in the API, it was not documented as such.

2018-02-22media: vidioc-g-parm.rst: also allow _MPLANE buffer typesHans Verkuil1-3/+4
The specification mentions that type can be V4L2_BUF_TYPE_VIDEO_CAPTURE, but the v4l2 core implementation also allows the _MPLANE variant. Document this.

2017-09-05media: v4l uAPI: add descriptions for arguments to all ioctlsMauro Carvalho Chehab1-0/+1
Several ioctls are missing descriptions for the third argument of the ioctl() command. They should have a description, as otherwise the output won't be ok, and will sound like something is missing. So, add them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-22[media] v4l: doc: Remove row numbers from tablesLaurent Pinchart1-235/+137
Shorten the tables by removing row numbers in comments, allowing for later insertion of rows with minimal diffs. All changes have been generated by the following script. import io import re import sys def process_table(fname, data): if fname.endswith('hist-v4l2.rst'): data = re.sub(u'\n{1,2}\t( ?) -( ?) ?', u'\n\t\\1 -\\2', data, flags = re.MULTILINE) data = re.sub(u'\n(\t| )- \.\. row [0-9]+\n\t ?-( ?) ?', u'\\1* -\\2', data, flags = re.MULTILINE) else: data = re.sub(u'\n{1,2} -( ?) ?', u'\n -\\1', data, flags = re.MULTILINE) data = re.sub(u'(\n?)(\n\n - \.\. row 1\n)', u'\n\\2', data, flags = re.MULTILINE) data = re.sub(u'\n - \.\. row [0-9]+\n -( ?) ?', u' * -\\1', data, flags = re.MULTILINE) data = re.sub(u'\n - \.\. row [0-9]+\n \.\.

2016-09-09[media] docs-rst: fix cross-references for videodev2.hMauro Carvalho Chehab1-1/+1
There are several broken references there, due to the conversion to C domain. Fix them using this shell script and manually adjust what's broken: # funcs is a file with the broken functions/references for i in $(cat funcs|sort|uniq|perl -ne 'print "$1\n" if (m/(\S+)$/)'); do i=${i//-/_} echo $i j=${i//_/-} for k in $(git grep -l "_$j:" Documentation/); do sed s,\_$j\:,"c\:type\:\: $i", <$k >a && mv a $k done for k in $(git grep -l "$j" Documentation/media/*.exceptions); do sed s,$j,":c\:type\:\`$i\`", <$k >a && mv a $k done for k in $(git grep -l "$j" Documentation/); do sed "s,:ref:\`$i <$j>\`,:c:type:\`$i\`," <$k >a && mv a $k sed "s,:ref:\`$j\`,:c:type:\`$i\`," <$k >a && mv a $k sed -E "s,:ref:\`(.*)<$j>\`,:c:type:\`\1<$i>\`," <$k >a && mv a $k done for k in $(git grep -l "<$j>" include/media); do sed -E "s,:ref:\`(.*)<$j>\`,enum \&$i," <$k >a && mv a $k done done Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] docs-rst: simplify c:type: cross referencesMauro Carvalho Chehab1-1/+1
Instead of using c:type:`struct foo <foo>`, use: struct c:type:`foo` This patch was generated via this shell script: for i in `find Documentation/media -type f`; do perl -ne 'if (m/\:c\:type\:\`struct\s+(\S+)\s*\<(\S+)\>\`/) { $s=$1; $r=$2; if ($s eq $r) { s/\:c\:type\:\`struct\s+(\S+)\s*\<(\S+)\>\`/struct :c:type:`$2`/; s/struct\s+struct/struct/; s/(struct\s+\:c\:type\:\`\S+\`)\s+structure/$1/; }} print $_' <$i >a && mv a $i; done Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] docs-rst: convert uAPI structs to C domainMauro Carvalho Chehab1-11/+11
instead of declaring the uAPI structs using usual refs, e. g.: .. _foo-struct: Use the C domain way: .. c:type:: foo_struct This way, the kAPI documentation can use cross-references to point to the uAPI symbols. That solves about ~100 undefined warnings like: WARNING: c:type reference target not found: foo_struct Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-23[media] docs-rst: Convert V4L2 uAPI to use C function referencesMauro Carvalho Chehab1-4/+5
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. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-23[media] docs-next: stop abusing on the cpp domainMauro Carvalho Chehab1-1/+1
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>
2016-08-22[media] docs-rst: fix warnings introduced by LaTeX patchsetMauro Carvalho Chehab1-10/+10
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] docs-rst: add tabularcolumns to all tablesMauro Carvalho Chehab1-0/+10
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>
2016-07-13Revert "[media] docs-rst: escape [] characters"Mauro Carvalho Chehab1-3/+3
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.
2016-07-12[media] docs-rst: escape [] charactersMauro Carvalho Chehab1-3/+3
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>
2016-07-08doc_rst: rename the media Sphinx suff to Documentation/mediaMauro Carvalho Chehab1-0/+349
The name of the subsystem is "media", and not "linux_tv". Also, as we plan to add other stuff there in the future, let's rename also the media uAPI book to media_uapi, to make it clearer. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
