media: Explicitly include correct DT includes

2023-07-19T10:57:51+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

media: vde: Convert to platform remove callback returning void

2023-04-11T14:59:15+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by: Uwe Kleine-König Signed-off-by: Hans Verkuil

In preparation for adding field decoding support, convert the byte arrays for reflist into array of struct v4l2_h264_reference. That struct will allow us to mark which field of the reference picture is being referenced.

media: Kconfig: cleanup VIDEO_DEV dependencies

2022-03-18T04:58:35+00:00

media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.
