changeset 6c96dbbc added a new function that seems to be a modified version of an existing function. That's ok, but it was adding a "word" var from the previous code that it is not used on the new function. So, remove this left-over. Signed-off-by:

Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer. Add new member variables - bytesused, length, offset, userptr, fd, data_offset - to struct vb2_plane in order to cover all information of v4l2_plane. struct vb2_plane { <snip> unsigned int bytesused; unsigned int length; union { unsigned int offset; unsigned long userptr; int fd; } m; unsigned int data_offset; } Replace v4l2_buf with new member variables - index, type, memory - which are common fields for buffer management. struct vb2_buffer { <snip> unsigned int index; unsigned int type; unsigned int memory; unsigned int num_planes; struct vb2_plane planes[VIDEO_MAX_PLANES]; <snip> }; v4l2 specific fields - flags, field, timestamp, timecode, sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c struct vb2_v4l2_buffer { struct vb2_buffer vb2_buf; __u32 flags; __u32 field; struct timeval timestamp; struct v4l2_timecode timecode; __u32 sequence; }; Signed-off-by:Junghak Sung <jh1009.sung@samsung.com> Signed-off-by:

Make videobuf2-v4l2 as a wrapper of videobuf2-core for v4l2-use. And replace videobuf2-core.h with videobuf2-v4l2.h. This renaming change should be accompanied by the modifications of all device drivers that include videobuf2-core.h. It can be done with just running this shell script. replace() { str1=$1 str2=$2 dir=$3 for file in $(find $dir -name *.h -o -name *.c -o -name Makefile) do echo $file sed "s/$str1/$str2/g" $file > $file.out mv $file.out $file done } replace "videobuf2-core" "videobuf2-v4l2" "include/media/" replace "videobuf2-core" "videobuf2-v4l2" "drivers/media/" replace "videobuf2-core" "videobuf2-v4l2" "drivers/usb/gadget/" replace "videobuf2-core" "videobuf2-v4l2" "drivers/staging/media/" Signed-off-by: -

When trying to use v4l2_ctrl_g_ctrl_int64() to retrieve a V4L2_CTRL_TYPE_INTEGER64 type value the internal helper function get_ctrl() would prematurely exit because for this control type the 'is_int' flag is not set. This would result in v4l2_ctrl_g_ctrl_int64 always returning 0. Also v4l2_ctrl_g_ctrl_int64() is reading and returning the 32bit value member instead of the 64bit version, so fixing that as well. This patch extends the condition check to allow the V4L2_CTRL_TYPE_INTEGER64 type to continue processing instead of exiting. Signed-off-by:

JPEG IP found in Exynos5433 is similar to what is in Exynos4, but there are some subtle differences which this patch takes into account. The most important difference is in what is processed by the JPEG IP and what has to be provided to it. In case of 5433 the IP does not parse Huffman and quantisation tables, so this has to be performed with the CPU and the majority of the code in this patch does that. A small but important difference is in what address is passed to the JPEG IP. In case of 5433 it is the SOS (start of scan) position, which is natural, because the headers must be parsed elsewhere. There is also a difference in how the hardware is put to work in device_run. Data structures are extended as appropriate to accommodate the above changes. Signed-off-by:

Allow jpeg codec variants declare clocks they need. Before this patch is applied jpeg-core gets jpeg->sclk "speculatively": if it is not there, we assume no problem. This patch eliminates this by explicitly declaring what clocks are needed for each variant. This is a preparation for adding Exynos 5433 variant support, which needs 4 clocks of names not compatible with any previous version of jpeg hw module. [Rebase and commit message] Signed-off-by:

The driver is using -1 instead of the -ENOMEM defined macro to specify that a buffer allocation failed. Since the error number is propagated, the caller will get a -EPERM which is the wrong error condition. Also, the smatch tool complains with the following warning: gen_mjpeghdr_to_package() warn: returning -1 instead of -ENOMEM is sloppy Signed-off-by:

The SPI core always reports the MODALIAS uevent as "spi:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: SPI id table or OF match table). So drivers needs to export the SPI id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added. But this means that OF-only drivers needs to have both OF and SPI id tables that have to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. Which can lead to issues if two vendors use the same SPI device name for example. To avoid the above, the SPI core behavior may be changed in the future to not require an SPI device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table even when is unused now to prevent breaking module loading when the core changes. Signed-off-by:

- Add missing V4L2_CTRL_TYPE_U32 documentation - Remove 'which are actually different on the hardware' sentence which is confusing. I think the idea was to let the user know that the step can be different for different hardware, but that's obvious because otherwise you wouldn't need to specify the step value. - Clarify that V4L2_CTRL_COMPOUND_TYPES also applies to arrays. Signed-off-by:

Hans Verkuil authored
Array controls weren't skipped when only V4L2_CTRL_FLAG_NEXT_CTRL was provided (so no V4L2_CTRL_FLAG_NEXT_COMPOUND was set). This is wrong since arrays are also considered compound controls (i.e. with more than one value), and applications that do not know about arrays will not be able to handle such controls. Fix the test to include arrays. Signed-off-by:

This is a preparation for a change to the type of v4l2 timestamps. v4l2_get_timestamp() is a helper function that reads the monotonic time and stores it into a 'struct timeval'. Multiple drivers implement the same thing themselves for historic reasons. Changing them all to use v4l2_get_timestamp() is more consistent and reduces the amount of code duplication, and most importantly simplifies the following changes. Signed-off-by:

Arnd Bergmann authored
The exynos4 fimc capture driver claims to use monotonic timestamps but calls ktime_get_real_ts(). This is both an incorrect API use, and a bad idea because of the y2038 problem and the fact that the wall clock time is not reliable for timestamps across suspend or settimeofday(). This changes the driver to use the normal v4l2_get_timestamp() function like all other drivers. Signed-off-by:

Fix various v4l2-compliance issues in the formatting ioctls: - the vbi device implemented video format ioctls which make no senses for a vbi device, remove them. - remove the unused ts_packet_size and ts_packet_count fields. - fill in colorspace and field. - fill in sizeimage with a default value. - for the video node the get, set and try format functions all do the same thing, so combine into a single function.

Now that saa7164 uses v4l2_fh and that poll() has been fixed, it is trivial to add support for control events. Signed-off-by:

- poll doesn't return negative values, so you can't return -EINVAL. Instead return POLLERR. - poll can't be called if !video_is_registered(), so this test can be dropped. - poll can never do a blocking wait, so remove that check. - poll shouldn't attempt to start streaming if the caller isn't interested in read events.
