The vivi.c driver has long gone, but v4l2-videobuf.rst still refers to it. Just drop that reference since it is no longer valid or relevant (videobuf is deprecated). The QUERYCAP documentation also made a reference to is, but there vivi could just be replaced by vivid, the vivi successor. Signed-off-by:

The Request API isn't meant to be chosen by users, but instead should be selected by drivers that want to support it. Hantro and Cedrus are already selecting the right options, so only the test drivers need to be fixed. Signed-off-by:

There are *lots* of I2C ancillary drivers. While we're using comments to group them, all options appear at the same menu. It should be a lot clearer to group them into sub-menus, with may help people to go directly to the driver(s) he's needing to enable. Suggested-by:

This file was converted from text at the early ReST days. We learnt a lot about how to produce a nicer result while keeping the file better readable as plain text. Change some ReST markups to make it look better, both at the output formats and as plain text file. While here, remove references for the old bt848/winutil tool, as it seems that it doesn't exist anymore. Signed-off-by: -

Right now, both V4L and Digital TV are shown as main titles. Instead, add a main title, in order to better display its output. While here, simplify the file, as we don't need to add a title for the indexes, nor we need copyright info, as everything there is GPL, as stated by the SPDX tags. Signed-off-by: -

This file is very old, and doesn't match the current udev behavior. I wanted to preserve it, because we'll need some udev description some day about how to keep names unique, but there's nothing here to help with that... So, be it: let's just discard this document, as it doesn't provide anything useful anymore. Signed-off-by: -

There aren't much to be done here... almost everything is still valid. The supported boards even reflect the current driver's state. Yet, some things changed, so let's keep this document updated. Signed-off-by: -

This document is... old. The bttv driver was one of the first drivers at the Kernel. So, the document became a little obsoleted. Update it to reflect some changes that happened along the time affecting this driver and the subsystem. Signed-off-by: -

This document is very outdated, and doesn't match the upstream current way. Update it, making some parts a little bit more generic. While the main focus of this document is digital TV cards, its content also may also help someone with just analog TV support. Signed-off-by: -

While this is old, now that we moved the intro part of it, its contents seem to be valid, if we mention that we're talking only about the BT878 support. Update the document title accordingly and remove the obsolete note from it. Signed-off-by: -

Include test_drivers/Kconfig when MEDIA_TEST_SUPPORT is enabled rather than MEDIA_PLATFORM_SUPPORT. Test drivers should not depend on platform drivers to be enabled. Reported-by:

Most CEC platform drivers are using VIDEO_*_CEC pattern, some with an _HDMI extension too. Well, they're not related to V4L2 support, and we don't really need those big config names. So drop VIDEO_* from them, remove _HDMI (if present) and move CEC to the start. This way, all platform driver options are now CEC_<driver>. Acked-by:

As CEC support doesn't depend on MEDIA_SUPPORT, let's place the platform drivers outside the media menu. As a side effect, instead of depends on USB, drivers just select it. Acked-by:

The only item that opens at the CEC Kconfig menu is related to Remote Controller. Also, its support should not depend on media support, so it makes sense to keep both RC and CEC together. After this change, the main media menus that are visible under "Device Drivers" menu are: <*> Remote Controller support ---> [ ] HDMI CEC RC integration (NEW) < > HDMI CEC drivers <M> Multimedia support ---> Acked-by:

The stop-state timeout needs to be over 100us as per CSI spec. With the CAL fclk of 266 MHZ on DRA76, with the current value the driver uses, the timeout is 24us. Too small timeout will cause failure to enable the streaming. Also, the fclk can be different on other SoCs, as is the case with AM65x where the fclk is 250 MHz. This patch fixes the timeout by calculating it correctly based on the fclk rate. Signed-off-by:

Sometimes there is a timeout when waiting for the Stop-State. Testing shows that sometimes we need to wait more than what the current code does. It is not clear how long this wait can be, but it is based on how quickly the sensor provides a valid clock, and how quickly CAL syncs to it. Change the code to make it more obvious how long we'll wait, and set a wider range for usleep_range. Increase the timeout to 750ms. Signed-off-by:

CAL_CSI2_CTX register has LINES field, which, according to the documentation, should be programmed to the number of lines transmitted by the camera. If the number of lines is unknown, it can be set to 0. The driver sets the field to 0 for some reason, even if we know the number of lines. This patch sets the number of lines properly, which will allow the HW to discard extra lines (if the sensor would send such for some reason), and, according to documentation: "This leads to regular video timings and avoids potential artifacts".
