The tpf_min (1/100) and tpf_max (100/1) are used as the lowest and the highest allowable value for the desired frame period in vivid_vid_cap_s_parm(). But the comparison between these values is unnecessary because the compared value is already chosen from webcam_intervals[] (from 1/60 to 1/1). Cc: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by:

We were getting the codec interface through a proxy function that does not bring anything compared to just accessing the interface definition directly, so just do that. Also make the decoder interfaces const. Signed-off-by:

The interface used to communicate with the firmware casts pointers into unsigned longs and back again in order to store private references, all of this for pointers that remain purely in the kernel. Replace these unsigned longs with void pointers to make the code a bit sturdier and easier to follow. Also simplify some interfaces by removing arguments that could be infered from others.

Remove redundant Makefile rules (vimc_capture-objs, ...). Stop exposing vimc-{common, streamer} as modules, since there's no use case where they would be individually added/removed from Vimc. As consequence, remove MODULE_ macros from vimc-{common, streamer}. `-objs` is fitted for building host programs, change to `-y`, more straightforward for device drivers.

This paragraph was added by commit a42b57f5 ("V4L/DVB: Documentation: add v4l2-controls.txt documenting the new controls API") back in 2010, when the controls API has been improved. Nowadays it is a bit anachronistic, so remove it. The same information is stated in up-to-date wording a few paragraphs later > You’re done! And this is sufficient for most of the drivers we have. No > need to do any validation of control values, or implement QUERYCTRL, > QUERY_EXT_CTRL and QUERYMENU. And G/S_CTRL as well as G/TRY/S_EXT_CTRLS > are automatically supported. Signed-off-by:

The code snippet showing how to add controls to the driver’s top-level struct is present twice, but only the second time it is split in the V4L2 and subdev cases. Consolidate everything at the beginning. Also remove the "Where foo->bar is of type struct baz" sentences, this obvious from the code. Signed-off-by:

Since the beginning the second clock ('special', 'sclk') was optional and it is not available on some variants of Exynos SoCs (i.e. Exynos5420 with v7 of MFC hardware). However commit 1bce6fb3 ("[media] s5p-mfc: Rework clock handling") made handling of all specified clocks mandatory. This patch restores original behavior of the driver and fixes its operation on Exynos5420 SoCs.

Fix v4l2_fourcc define to use "U" cast to avoid shifting signed 32-bit value by 31 bits problem. This isn't a problem for kernel builds with gcc. This could be problem since this header is part of public API which could be included for builds using compilers that don't handle this condition safely resulting in undefined behavior.

This splits the Atmel ISC driver into a common base: atmel-isc-base.c and the driver probe/dt part , atmel-sama5d2-isc.c This is needed to keep a common ground for the sensor controller which will be reused. The atmel-isc will use the common symbols inside the atmel-isc-base Future driver will also use the same symbols and redefine different aspects, for a different version of the ISC. This is done to avoid complete code duplication by creating a totally different driver for the new variant of the ISC. Signed-off-by:

When the application calls VIDIOC_DQBUF with the DMABUF memory type, the v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf file descriptors. However, the current documentation does not explain whether those are new file descriptors referring to the same DMA-bufs or just the same integers as passed to VIDIOC_QBUF back in time. Clarify the documentation that it's the latter. Signed-off-by:
