2019-06-21media: mtk-vcodec: remove unneeded proxy functionsAlexandre Courbot
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.

2019-06-21media: mtk-vcodec: avoid unneeded pointer-to-long conversionsAlexandre Courbot
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.

2019-06-21media: vimc: Makefile: file cleanupAndré Almeida
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.

2019-06-21media: s5p-mfc: Make additional clocks optionalMarek Szyprowski
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 1bce6fb3edf1 ("[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.

2019-06-11media: vicodec: improve handling of ENC_CMD_STOP/STARTHans Verkuil
Correctly handle stopping and restarting the encoder, keeping track of the stop and drain states. In addition it adds correct handling of corner cases, allowing v4l2-compliance to pass. Unfortunately, the code is getting to be quite complicated, so we need to work on better codec support in v4l2-mem2mem.c to simplify drivers.

2019-06-11media: vicodec: stateless codecs do not have EOS and SOURCE_CHANGE eventsHans Verkuil
Return an error when attempting to subscribe to those events for a stateless codec. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2019-06-11media: vicodec: use correct sizeimage value when drainingHans Verkuil
After a resolution change is detected, q_data->sizeimage is updated to the new format, but buf_prepare is still draining buffers that need to use the old pre-resolution-change value. So store the sizeimage value in q_data->vb2_sizeimage in queue_setup and use that in buf_prepare.

Set V4L2_BUF_FLAG_P/KEYFRAME after decoding a frame. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2019-06-11media: vicodec: add V4L2_CID_MIN_BUFFERS_FOR_OUTPUTHans Verkuil
The stateful encoder requires the presence of this control. Since a single buffer is sufficient for vicodec, we just set this control to 1. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2019-06-11media: vicodec: pass on enc output format to capture sideHans Verkuil
Setting the encoder output format to e.g. 1920x1080 will set the crop rectangle to 1920x1088, the coded resolution to 1920x1088 and the capture coded resolution and sizeimage to 1920x1088 as well. Note that this might change, since the encoder spec is still in flux with respect to how this should behave.

The initial sizeimage value was wrong for the stateless decoder. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2019-06-11media: vicodec: always return a valid format.Hans Verkuil
Rather than returning width/height values of 0, just default to a format. Formats in V4L2 are always supposed to be valid, there is no concept of an invalid format. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

v4l2_ctrl_request_complete can sleep, so can't be called while a spinlock is held. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
