v4l: vsp1: Set the SRU CTRL0 register when starting the stream

2016-04-20T06:45:21+00:00

commit f6acfcdc5b8cdc9ddd53a459361820b9efe958c4 upstream.

Commit 58f896d859ce ("[media] v4l: vsp1: sru: Make the intensity
controllable during streaming") refactored the stream start code and
removed the SRU CTRL0 register write by mistake. Add it back.

coda: fix error path in case of missing pdata on non-DT platform

2016-04-20T06:45:21+00:00

commit bc717d5e92c8c079280eb4acbe335c6f25041aa2 upstream.

If we bail out this early, v4l2_device_register() has not been called
yet, so no need to call v4l2_device_unregister().

coda: fix first encoded frame payload

2016-04-12T14:33:29+00:00

commit 74dc385cb450089b28c28be2c8a0baca296b95f9 upstream.

During the recent vb2_buffer restructuring, the calculation of the
buffer payload reported to userspace was accidentally broken for the
first encoded frame, counting only the length of the headers.
This patch re-adds the length of the actual frame data.

[media] exynos4-is: make VIDEO_SAMSUNG_EXYNOS4_IS tristate

2016-01-25T14:53:17+00:00

With CONFIG_V4L2=m and VIDEO_SAMSUNG_EXYNOS4_IS=y, we can select the
individual drivers as built-in code when that should not be possible:

drivers/built-in.o: In function `s5pcsis_set_fmt':
policy.c:(.text+0x13afdc): undefined reference to `v4l_bound_align_image'
drivers/built-in.o: In function `s5pcsis_probe':
policy.c:(.text+0x13b440): undefined reference to `v4l2_of_parse_endpoint'
policy.c:(.text+0x13b72c): undefined reference to `v4l2_subdev_init'

Changing VIDEO_SAMSUNG_EXYNOS4_IS to tristate means that the dependency
from CONFIG_V4L2 propates to the individual Kconfig symbols and they
can only be built as loadable modules if V4L2 or any other of the
dependencies itself is a module.

[media] media: Kconfig: add dependency of HAS_DMA

2016-01-25T12:32:47+00:00

The build of m32r allmodconfig fails with the error:
drivers/media/v4l2-core/videobuf2-dma-contig.c:484:2:
	error: implicit declaration of function 'dma_get_cache_alignment'

The build of videobuf2-dma-contig.c depends on HAS_DMA and it is
correctly mentioned in the Kconfig but the symbol VIDEO_STI_BDISP also
selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile
videobuf2-dma-contig.c even though HAS_DMA is not defined.

[media] exynos4-is: Wait for 100us before opening sensor

2016-01-25T12:30:12+00:00

Some user space use cases result in kernel hangup on the HIC_OPEN_SENSOR
command write. In case when a minimalistic application is used for setting
up the streaming, the hangups occur only occasionally. In case of GStreamer
use cases it is always the case.

[media] exynos4-is: Open shouldn't fail when sensor entity is not linked

2016-01-25T12:29:50+00:00

In order to allow for automatic media device entities linking
from the level of libv4l plugin the open system call shouldn't
fail, as the libv4l plugins can begin their job not until it
succeeds.
This patch allows for leaving the  pipeline not linked on
open and postpones verifying it to the moment when streamon
callback is called.

[media] exynos4-is: fix a format string bug

2016-01-25T11:20:16+00:00

Ironically, 7d4020c3c400 ("[media] exynos4-is: fix some warnings when
compiling on arm64") fixed some format string bugs but introduced a
new one. buf_index is a simple int, so it should be printed with %d,
not %pad (which is correctly used for dma_addr_t).
