2016-07-03doc-rst: pixfmt-uyvy: remove an empty columnMauro Carvalho Chehab
The conversion added an empty column (probably, it was used on DocBook just to increase spacing. Remove it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: pixfmt-y12i: correct format conversionMauro Carvalho Chehab
The format conversion broke one paragraph into two. Fix it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: linux_tv: remove trailing commentsMauro Carvalho Chehab
The conversion script added some comments at the end. They point to the original DocBook files, with will be removed after the manual fixes. So, they'll be pointing to nowere. So, remove those comments. They'll be forever stored at the Kernel tree. So, if someone wants the references, it is just a matter of looking at the backlog.

2016-07-03doc-rst: linux_tv: use references for structuresMauro Carvalho Chehab
On several places, instead of using references, the code was using some other tag. Not sure if this was due to the conversion, or if something were already wrong on the DocBook. In any case, let's fix them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: linux_tv: Error codes should be constMauro Carvalho Chehab
All error codes should be const. Most are, but there are lots of places where we forgot to add <constant> at the DocBook. Fix those via this small script: for i in $(git grep -lE "\s+E[A-Z]+\b" Documentation/linux_tv/); do perl -ne 's,([^\`])\b(E[A-Z]+)\b,\1``\2``,g; print $_' <$i >a && mv a $i; done As there are false positives, we needed to merge only the changes that make sense, skipping the c blocks and skipping things like EDID, EN, ETS that were also converted by the above code.

2016-07-03doc-rst: linux_tv: use Example x.y. instead of a single numberMauro Carvalho Chehab
On the example captions, use always <chapter>.<number>., because: 1) it matches the DocBook; 2) it would mean less changes if we need to add a new example, as only one chapter will be affected. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: selection-api-005: Fix ReST parsingMauro Carvalho Chehab
The ReST markup is limited: it doesn't accept a const just after a reference. So, change the documentation to avoid such constraint. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: crop: fix conversion on this fileMauro Carvalho Chehab
The conversion on this file didn't end too well. fix the found issues: 1) Sphinix seems to not allow things like *foo :ref:`bar`*. At least on this document, it did the wrong thing. So, change the logic to something that will work fine with ReST format; 2) Some ioctl pointers were not looking nice; 3) the captions on the examples got discarded; 4) The notes specific to each example were not converted well. Again, we'll need to replace it for a simpler design, as Sphinx is a way more limited than DocBook. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: planar-apis: fix some conversion troublesMauro Carvalho Chehab
There is a missing escape caracter, causing troubles at the format of one of the paragraphs. Also, the ioctl description was producing some warnings about wrong identation. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: linux_tv: supress lots of warningsMauro Carvalho Chehab
The c language parser checks if there are duplicated object definitions. That causes lots of warnings like: WARNING: duplicate C object description of ioctl Let's remove those by telling Sphinx that the language for those objects are c++. The look of the descriptions will be close, and the warnings will be gone. Please notice that we had to keep a few of them as C, as the c++ parser seems to be broken when it finds an enum. Yet, this reduced from 219 warnings to 143, with is a good thing. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-07-03doc-rst: vidioc-queryctl: change the title of this chapterMauro Carvalho Chehab
This chapter is referenced on several parts of the extended controls. Change the title to make it nicer where it is referenced. Ok, we might, instead, just change the name for the references to only mention the oldest ioctl, but IMHO, it is better to keep the name of all ioctls where it is referenced.

2016-07-03doc-rst: linux_tv: remove controlsMauro Carvalho Chehab

2016-07-03spi: spi-bfin-sport: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
The workqueue "workqueue" serves as a driver message queue. It has a single work item(&drv_data->pump_messages) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Work item has been flushed in bfin_sport_spi_destroy_queue() to ensure that there are no pending tasks while disconnecting the driver.

MCP466x This patch adds support for MCP454x, MCP456x, MCP464x and MCP466x parts.

The PM280 has an internal standby-mode, but to really save power we should shut the sensor down and disconnect the power. With the proper .pm hooks we can enable both runtime and system power management of the sensor. We use the *force callbacks from the system PM hooks. When the sensor comes back we always reconfigure it to make sure it is ready to roll as expected.
