f4ad8d74e1 [media] media: davinci: vpif: add check for NULL handler
for da850/omap-l138, there is no need to setup_input_channel_mode()
and set_clock(), to avoid adding dummy code in board file just returning
zero add a check in the driver itself to call the handler only if its
not NULL.

14783d2536 [media] s5p-fimc: Add support for V4L2_PIX_FMT_S5C_UYVY_JPG fourcc
The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the
first containing interleaved JPEG/YUYV data and the second containing
meta data describing the interleaving method.
The image data is transferred with MIPI-CSI "User Defined Byte-Based
Data 1" type and is captured to memory by FIMC DMA engine.
The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image
Data" and it is captured in the MIPI-CSI slave device and copied to
the bridge provided buffer.
To make sure the size of allocated buffers is correct for the subdevs
configuration when VIDIOC_STREAMON ioctl is invoked, an additional
check is added at the video pipeline validation function.
Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved
from a sensor subdev.

36fa809276 [media] s5p-csis: Add support for non-image data packets capture
MIPI-CSI has internal memory mapped buffers for the frame embedded
(non-image) data. There are two buffers, for even and odd frames which
need to be saved after an interrupt is raised. The packet data buffers
size is 4 KiB and there is no status register in the hardware where the
actual non-image data size can be read from. Hence the driver copies
whole packet data buffer into a buffer provided by the FIMC driver.
This will form a separate plane in the user buffer.
When FIMC DMA engine is stopped by the driver due the to user space
not keeping up with buffer de-queuing the MIPI-CSIS will still run,
however it must discard data which is not captured by FIMC. Which
frames are actually capture by MIPI-CSIS is determined by means of
the s_tx_buffer subdev callback. When it is not called after a single
embedded data frame has been captured and copied and before next
embedded data frame interrupt occurrs, subsequent embedded data frames
will be dropped.

b9ee31e621 [media] s5p-fimc: Add pipeline ops to separate FIMC-LITE module
In order to reuse the FIMC-LITE module on Exynos4 and Exynos5
SoC introduce a set of callbacks for the media pipeline control
from within FIMC/FIMC-LITE video node. It lets us avoid symbol
dependencies between FIMC-LITE and the whole media device driver,
which simplifies the initialization sequences and doesn't
introduce issues preventing common kernel image for exynos4 and
exynos5 SoCs.
This patch also corrects following build errors:

This is a piece of code becoming dead since commit 2c9ba37 ([media]
V4L: mx2_camera: remove unsupported i.MX27 DMA mode, make EMMA
mandatory).  It should have been removed together with the commit.
Remove it now.

0bd0dbee3f [media] omap3isp: Fix error return code in probe function
Convert a nonnegative error return code to a negative one, as returned
elsewhere in the function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
(
if@p1 (\(ret < 0\|ret != 0\))
 { ... return ret; }
|
ret@p1 = 0
)
... when != ret = e1
    when != &ret
*if(...)
{
  ... when != ret = e2
      when forall
 return ret;
}
// </smpl>

channel_first_int[][] variable is used as a flag for the ISR,
This flag was being set after enabling the interrupts, There
where situations when the isr occurred even before the flag was set
dues to which it was causing the application hang.
This patch sets  channel_first_int[][] flag just before enabling the
interrupt.

e34db0661d [media] media: coda: set up buffers to be sized as negotiated with s_fmt
This fixes a failure in vb2_qbuf in user pointer mode where
__qbuf_userptr checks if the buffer queued by userspace is large
enough. The failure would happen if coda_queue_setup was called
with empty fmt (and thus set the expected buffer size to the maximum
resolution), and userspace queues buffers of smaller size -
corresponding to the negotiated dimensions - were queued.
Explicitly setting sizeimage to the value negotiated via s_fmt
fixes the issue.
