2017-09-05media: gen-errors.rst: document ENXIO error codeMauro Carvalho Chehab1-0/+5
This error can be produced at least at the DVB subsystem. As it is generic enough, document it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: gen-errors.rst: remove row number commentsMauro Carvalho Chehab1-33/+11
Those are introduced by the conversion scripts and don't really help. Get rid of them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb uapi docs: better organize header filesMauro Carvalho Chehab8-60/+22
Instead of having one chapter per file, place all of them at the same chapter. That better organize the chapters at the uAPI documentation. As a side effect, now all uAPI headers are at the same page, at the html output, with makes easier to use it as a reference index for the spec. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb rst: identify the documentation gap at the APIMauro Carvalho Chehab2-0/+10
Now that DVB spec is almost in sync, document what's missing. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb CA docs: place undocumented data together with ioctlsMauro Carvalho Chehab3-61/+19
Right now, the same undocumented structs are on two places: at ca_data_types.rst and together with their ioctls. Move them to just one place and use the standard way to represent them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2017-09-05media: ca-reset.rst: add some description to this ioctlMauro Carvalho Chehab1-1/+2
While we don't have any documentation for it, based on what's there at Kaffeine and VDR, it seems that this command should be issued before start using CA. So, document it as such. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: ca.h: document most CA data typesMauro Carvalho Chehab1-65/+10
For most of the stuff there, documenting is easy, as the header file contains information. Yet, I was unable to document two data structs: ca_msg and ca_descr As those two structs are used by a few drivers, keep them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: ca.h: get rid of CA_SET_PIDMauro Carvalho Chehab5-77/+0
This ioctl seems to be some attempt to support a feature at the bt8xx dst_ca driver. Yet, as said there, it "needs more work". Right now, the code there is just a boilerplate. At the end of the day, no driver uses this ioctl, nor it is documented anywhere (except for "needs more work"). So, get rid of it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: net.rst: Fix the level of a section of the net chapterMauro Carvalho Chehab1-1/+0
Due to a mistake, the DVB net chapter was actually broken into two different chapters. Fix it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dmx.h: add kernel-doc markups and use it at Documentation/Mauro Carvalho Chehab2-172/+6
The demux documentation is pretty poor nowadays: most of the structs and enums aren't documented at all. Add proper kernel-doc markups for them and use it. Now, the demux API data structures are fully documented :-) Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dmx.h: get rid of GET_DMX_EVENTMauro Carvalho Chehab3-80/+0
This seems to be a pure fictional API :-) It only exists at the DVB book, with no code implemeting it. So, just get rid of it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dmx.h: get rid of DMX_SET_SOURCEMauro Carvalho Chehab4-78/+0
No driver uses this ioctl, nor it is documented anywhere. So, get rid of it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dmx.h: get rid of DMX_GET_CAPSMauro Carvalho Chehab4-55/+0
There's no driver currently using it; it is also not documented about what it would be supposed to do. So, get rid of it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dmx.h: get rid of unused DMX_KERNEL_CLIENTMauro Carvalho Chehab2-2/+0

2017-09-05media: fe_property_parameters.rst: better define properties usageMauro Carvalho Chehab1-7/+75
Several frontend properties are specific to a subset of the delivery systems. Make it clearer when describing each property. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb frontend docs: use kernel-doc documentationMauro Carvalho Chehab16-1855/+309
Now that frontend.h contains most documentation for the frontend, remove the duplicated information from Documentation/ and use the kernel-doc auto-generated one instead. That should simplify maintainership of DVB frontend uAPI, as most of the documentation will stick with the header file. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: adjust the notices about optional hardwareMauro Carvalho Chehab1-12/+17
Both CA and decoders are optional. Also, the presence or absence has nothing to do on being a PCI card or not. Nowadays, most hardware leaves the decoders to either the GPU or to some ISP inside the SoC, instead of implementing it inside the Digital TV part of the device. So, change the wording to reflect the hardware changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: update the history part of the documentMauro Carvalho Chehab1-6/+10
Convergence doesn't exist anymore. The community itself maintains the spec. Update accordingly. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: update references for TV standardsMauro Carvalho Chehab1-3/+6
The references there are only for DVB. Add missing references for ATSC and ISDB standards. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-09-05media: dvb/intro: use the term Digital TV to refer to the systemMauro Carvalho Chehab1-12/+12
On several places at the introduction, a digital TV board and its kernel support is called as DVB. The reason is simple: by the time the document was written, there were no other digital TV standards :-) Modernize the specs by referring to them as Digital TV.

2017-08-27media: dvbproperty.rst: improve notes about legacy frontend callsMauro Carvalho Chehab1-14/+25
The description of the DVBv5 API was written a long time ago, where the API was still new, and there were not apps using it. Now that the API is stable and used by new applications, clarify that DVBv3 calls should not be used and why. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-08-27media: frontend.rst: mention MMT at the documentationMauro Carvalho Chehab1-3/+2
The ATSC 3.0 uses MPEG Media Transport, with is not currently supported. Yet, we'll need to implement it sooner or later. So, mention about it at the specs. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-08-27media: frontend.rst: convert SEC note into footnoteMauro Carvalho Chehab1-8/+11
The description of what SEC means fits well as a footnote. That makes the need of saying that SEC is only for Satellite when it was mentioned, as the footnote already says that. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-08-27media: frontend.rst: fix supported delivery systemsMauro Carvalho Chehab1-3/+5
The introduction for the frontend chapter is not quite correct: - it tells that it supports only three types of delivery systems, in opposite to three *groups*; - It adds ISDB-C to the list of supported systems, but, this is not true. Fix it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2017-08-27media: dvb/intro.rst: Use verbatim font where neededMauro Carvalho Chehab1-2/+2
The device numbering for DVB uses "M" and "N" as vars for the number of the device, but sometimes this is printed using normal font instead of verbatim. While here, remove an extra space after quotation marks. This is a minor cleanup with no changes at the text. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2017-08-27media: fix pdf build with Spinx 1.6Mauro Carvalho Chehab20-167/+202
Sphinx 1.6 generates some LaTeX code before each table, starting its own environment before calling tabulary, apparently to improve table layout. The problem is that such environment is incompatible with adjustbox. While, in thesis, it should be possible to override it or to redefine tabulary, I was unable to produce such patch. Also, that would likely break on some future Sphinx version. So, instead, let's just change the font size on bigger tables, in order for them to fit into the page size. That is not as good as adjustbox, and require some manual work, but it should be less sensitive to Sphinx changes. While here, adjust a few other tables whose text is exceeding the cell boundaries.

The CEC_EVENT_PIN_LOW/HIGH defines and the cec_queue_pin_event() function did not specify that these were about CEC pin events. Since in the future there will also be HPD pin events it is wise to rename the event defines and function to CEC_EVENT_PIN_CEC_LOW/HIGH and cec_queue_pin_cec_event() now before these become part of the ABI.

2017-08-08media: media/doc: rename and reorder pixfmt filesHans Verkuil8-40/+37
After the DocBook conversion a number of pixfmt description files just had a number in the filename (pix-fmt-004, 006, etc) which was not very descriptive. Rename them. Note that pixfmt-008.rst was folded into colorspaces-details.rst, so that file is deleted. It's easier to maintain that way. Also moved the colorspace sections to the end of the chapter. The old order was weird: the "Standard Image Formats" section (an intro into pixel formats) was followed by the colorspace sections instead of the pixel format descriptions. Moving it to the end resolved that issue. Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
