for the xml files describing ioctls, use the same nomenclature as on V4L2: the ioctl name, in lower case, using - instead of _. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

The new code that detects undocumented ioctls hits some false positives: This one is not documented, nor it should, as this is there just to reserve namespace: Warning: can't find reference for VIDIOC_RESERVED ioctl But those are already documented together with other ioctls: Warning: can't find reference for VIDIOC_UNSUBSCRIBE_EVENT ioctl Warning: can't find reference for FE_GET_PROPERTY ioctl Warning: can't find reference for VIDIOC_SUBDEV_G_EDID ioctl Warning: can't find reference for VIDIOC_SUBDEV_S_EDID ioctl Warning: can't find reference for VIDIOC_SUBDEV_S_DV_TIMINGS ioctl Warning: can't find reference for VIDIOC_SUBDEV_G_DV_TIMINGS ioctl Warning: can't find reference for VIDIOC_SUBDEV_QUERY_DV_TIMINGS ioctl So, we need to just be sure to point to the right documentation.

There are several badly documented undocumented ioctls. Currently, it just generates an empty link. Instead of doing that, only add references to the ones that exists, and add a warning for all references that weren't found. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Instead of having two refentries, merge them into just one, like what's done with other similar ioctls at V4L2 side. That makes the entry cleaner and will allow to add the associated structures together with the refentry. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Instead of going to the V4L2 open(), use the xref to the proper place at the frontend ioctls that were already reformatted. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

The DVBv5 API uses DVB properties as the main way to set the frontend and collect statistics. Move the definition to happen earlier, in order to reflect its importance. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Move the ioctl and enum fe_status to a separate xml file and put it into a better format. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Keeping everything altogether makes harder to reorganize the DocBook. So, move the FE_GET_INFO ioctl and the associated structures into a separate file. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Mauro Carvalho Chehab authored
The DVB part of the docbook has a completely different format than the V4L2 part, as it was written as a separate document. As the V4L2 documentation is on better shape, and its format allows adding more information, let's use it for FE_GET_INFO and gradually update the non-legacy DVB ioctls using the new format.

Using typedefs is already bad enough, but doing it together with enum declaration is even worse. Also, it breaks the scripts at DocBook that would be generating reference pointers for the enums. Well, we can't get rid of typedef right now, but let's at least declare it on a separate line, and let the scripts to generate the cross-reference, as this is needed for the next DocBook patches.

Although the recommended usage is the DVBv5 API calls, the documentation doesn't make it clear about what's the recommended calls and what's legacy. So, move the legacy API bits to a separate xml, putting them into a new section. Please notice that more changes are needed, since some of the bits there are cross-referenced elsewhere.

Currently, it is using 'role="tt"', but this is not defined at the DocBook 4.5 spec. The net result is that no emphasis happens. So, replace them to bold emphasis. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

The Docbook mistakenly makes to believe that all needed APIs for media devices are there. Add a note there pointing that some sub-devices are actually be controlled via ALSA API. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

The list of standards at the media docbook is incomplete, and it is mentioning that the DVB-S2 & friends is "currently being updated". That's wrong, as such update occurred back in 2008. So, provide a more complete list of supported standards and add a reference to the actual list. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* Rename device state from 's' to 'dev'. * Move single include to driver private header. * Change error handling type of each function to one I tend use nowadays. * Remove dummy register write from init. Even Windows driver does this multiple times remove it as I have never seen any I2C errors. * Define I2C client pointer for each function and use it. * Do not clean tuner ops during driver remove - not needed. * Disable sysfs device bind / unbind. We are not allowed manually bind / unbind device from the driver currently. * Rename some other variables.

Update synthesizer calculation to model I prefer nowadays. It is mostly just renaming some variables to ones I think are most standard.

This code works fine but static checkers complain. The test_bit() function takes the bit number and not a mask. Then the other issue is that we were using USB_STATE_URB_BUF which is BIT(0) instead of URB_BUF. Also we were open coding that instead of using the test/clear/set_bit() functions.

The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a connector that can be used to hook up an adv7511 transmitter or an adv7842 receiver daughterboard. This device is used within Cisco but is sadly not available outside of Cisco. Nevertheless it is a very interesting driver that can serve as an example of how to support HDMI hardware and how to use the popular adv devices.

All drivers use custom notifications, in particular when source changes. The bridge only has to map the subdev that sends it to whatever video node it is connected to.

vb2_buffer_done() already allows STATE_QUEUED, but currently only when not streaming. It is useful to allow it while streaming as well, as this makes it possible for drivers to requeue buffers while waiting for a stable video signal.

Replace the dummy video format operations by pad format operations that configure the output format. Copied from the adv7604 driver. Note: while arch/blackfin/mach-bf609/boards/ezkit.c uses adv7842_platform_data this source has not been updated because it is broken since the very beginning. It depends on a struct adv7842_output_format that does not exist. And besides that gcc has no support for bf609 so nobody can compile it except by installing a toolchain from ADI.
