2016-08-24[media] v4l2-tpg-core: drop SYCC, use higher precision 601 conversion matrixHans Verkuil
The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the SYCC define is about to be removed for use in the kernel we need to drop it in the TPG code as well. This patch also adds a 4th decimal to the 601 conversion matrix. That was specified by the sYCC spec and it makes sense to use this across the board.

2016-08-23[media] v4l2-core: Add support for touch devicesNick Dyer
Some touch controllers send out touch data in a similar way to a greyscale frame grabber. Add new device type VFL_TYPE_TOUCH: - This uses a new device prefix v4l-touch for these devices, to stop generic capture software from treating them as webcams. Otherwise, touch is treated similarly to video capture. - Add V4L2_INPUT_TYPE_TOUCH - Add MEDIA_INTF_T_V4L_TOUCH - Add V4L2_CAP_TOUCH to indicate device is a touch device Add formats: - V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas - V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas - V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data - V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data This support will be used by: - Atmel maXTouch (atmel_mxt_ts) - Synaptics RMI4. - sur40 Signed-off-by: Nick Dyer <nick@shmanahar.org> Tested-by: Chris Healy <cphealy@gmail.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-08-22[media] index.rst: Fix LaTeX error in interactive mode on Sphinx 1.4.xMauro Carvalho Chehab
The Sphinx 1.4.x definition for \DUrole is: \providecommand*{\DUrole}[2]{% \ifcsname DUrole#1\endcsname% \csname DUrole#1\endcsname{#2}% \else% backwards compatibility: try \docutilsrole#1{#2} \ifcsname docutilsrole#1\endcsname% \csname docutilsrole#1\endcsname{#2}% \else% #2% \fi% \fi% } This is broken when it is used inside a \begin{alltt} block. So, replace it by just "#2", as this won't cause troubles, and it is one of the fallback methods for it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2016-08-22docs-rst: Use better colors for note/warning/attention boxesMauro Carvalho Chehab
Instead of painting the box with gray, let's use a colored box. IMHO, that makes easier to warn users about some issue pointed by the Sphinx.

2016-08-22docs-rst: conf.py: adjust the size of .. note:: tagMauro Carvalho Chehab

2016-08-22doc-rst: migrate ioctl CEC_DQEVENT to c-domainMarkus Heiser
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>
2016-08-22doc-rst: moved *duplicate* warnings to nitpicky modeMarkus Heiser
Moved the *duplicate C object description* warnings for function declarations in the nitpicky mode. In nitpick mode, you can suppress those warnings (e.g. ioctl) with:: nitpicky = True nitpick_ignore = [ ("c:func", "ioctl"), ] See Sphinx documentation for the config values for ``nitpick`` and ``nitpick_ignore`` [1]. With this change all the ".. cpp:function:: int ioctl(..)" descriptions (found in the media book) can be migrated to ".. c:function:: int ioctl(..)", without getting any warnings. E.g.:: .. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp ) .. c:function:: int ioctl( int fd, int request, struct cec_event *argp ) The main effect, is that we get those *CPP-types* back into Sphinx's C- namespace and we need no longer to distinguish between c/cpp references, when we refer a function like the ioctl.

2016-08-22doc-rst:c-domain: ref-name of a function declarationMarkus Heiser
Add option 'name' to the "c:function:" directive. With option 'name' the ref-name of a function can be modified. E.g.:: .. c:function:: int ioctl( int fd, int request ) :name: VIDIOC_LOG_STATUS The func-name (e.g. ioctl) remains in the output but the ref-name changed from ``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for this function is also changed to ``VIDIOC_LOG_STATUS`` and the function can now referenced by:: :c:func:`VIDIOC_LOG_STATUS` Signed-off-by: Markus Heiser <markus.heiser@darmarIT.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2016-08-22[media] subdev-formats.rst: adjust tables size for LaTeX outputMauro Carvalho Chehab
There are two big tables here that are very hard to adjust its size. The first one would fit into one page, but the latex.py logic at Sphinx auto-switches to longtable when there are more than 30 rows. There's no way to override without coding. The second one is really big, and won't fit on a single page. So, it has to use tiny font to fit. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-08-22[media] extended-controls.rst: avoid going past page with LaTeXMauro Carvalho Chehab
It is painful to put code/verbatim code in bold. It seems that the only way is to arrange it like: ``foo`` bar At least on LaTeX output, when this happens, the "foo" string is not hidentable/breakable. The entire string should fit into a single line. Add a workaround for this ReST limitation by splitting the foo string into two strings, on separate lines. The output is not the best, but it works.
