2016-08-23[media] Input: atmel_mxt_ts - read touchscreen sizeNick Dyer1-6/+36
The touchscreen may have a margin where not all the matrix is used. Read the parameters from T9 and T100 and take account of the difference. Note: this does not read the XORIGIN/YORIGIN fields so it assumes that the touchscreen starts at (0,0) Signed-off-by: Nick Dyer <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]> Acked-by: Dmitry Torokhov <[email protected]>

2016-08-23[media] Input: atmel_mxt_ts - add support for T37 diagnostic dataNick Dyer2-0/+165
Atmel maXTouch devices have a T37 object which can be used to read raw touch deltas from the device. This consists of an array of 16-bit integers, one for each node on the touchscreen matrix.

2016-08-23[media] v4l2-core: Add support for touch devicesNick Dyer7-9/+58
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 <[email protected]> Tested-by: Chris Healy <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]> Acked-by: Dmitry Torokhov <[email protected]>

2016-08-23[media] rcar-vin: move media bus information to struct rvin_graph_entityNiklas Söderlund4-16/+17
The primary reason for this change is to prepare for Gen3 support where there will be more then one possible video source. Each source will have its own media bus format and code, so it needs to be moved from the per device structure to a structure used to represent an individual connection to a video source.

2016-08-23[media] rcar-vin: rework how subdevice is found and boundNiklas Söderlund2-129/+111
The original drivers code to find a subdevice by looking in the DT grpah and how the callbacks to the v4l2 async bind framework where poorly written. The most obvious example of badness was the duplication of data in the struct rvin_graph_entity. This patch removes the data duplication, simplifies the parsing of the DT graph and add checks to the v4l2 callbacks.

2016-08-23[media] rcar-vin: move chip check for pixelformat supportNiklas Söderlund2-5/+8
The check for if the specific pixelformat is supported on the current chip should happen in VIDIOC_S_FMT and VIDIOC_TRY_FMT and not when we try to setup the hardware for streaming.

Fix a error from the original driver where v4l2_device_call_until_err() where used for the pad specific v4l2 operation set_fmt. Also fix up the error path from this fix so if there is an error it will be propagated to the caller.

2016-08-23[media] rcar-vin: rename entity to digitalNiklas Söderlund2-26/+26

2016-08-22[media] index.rst: Fix LaTeX error in interactive mode on Sphinx 1.4.xMauro Carvalho Chehab1-0/+5
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 <[email protected]>

2016-08-22docs-rst: Use better colors for note/warning/attention boxesMauro Carvalho Chehab1-10/+24
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 Chehab1-1/+7
While the current implementation works well when using as a paragraph, it doesn't work properly if inside a table.

2016-08-22docs-rst: add support for LaTeX outputMauro Carvalho Chehab3-2/+8

2016-08-22doc-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 <[email protected]> Signed-off-by: Jonathan Corbet <[email protected]>

This reverts commit a88b1672d4ddf9895eb53e6980926d5e960dea8e. From the origin comit log:: The RST cpp:function handler is very pedantic: it doesn't allow any macros like __user on it Since the kernel-doc parser does NOT make use of the cpp:domain, there is no need to change the kernel-doc parser eleminating the address_space tags.

2016-08-22doc-rst: moved *duplicate* warnings to nitpicky modeMarkus Heiser1-0/+27
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 Heiser2-0/+60
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 <[email protected]> Signed-off-by: Jonathan Corbet <[email protected]>

2016-08-22[media] subdev-formats.rst: adjust tables size for LaTeX outputMauro Carvalho Chehab1-6/+30
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 <[email protected]>
2016-08-22[media] extended-controls.rst: avoid going past page with LaTeXMauro Carvalho Chehab1-54/+213
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.
