4ad34da030 [media] gspca: the field 'frozen' is under CONFIG_PM
The gspca_dev field 'frozen' is added only if CONFIG_PM is set. So add the
relevant #ifdef's to various subdrivers that use it.

The m32r daily build caught this mistake.

4af813108b [media] s5p-fimc: Add support for Exynos4x12 FIMC-LITE
This patch adds driver for FIMC-LITE camera host interface. This new IP
differs from the regular FIMC IP in that it doesn't have input DMA,
scaler and color space conversion support. So it just plain camera host
interface for MIPI-CSI2 and ITU-R interfaces. For the serial bus support
it interworks with MIPI-CSIS and the exisiting s5p-csis driver.
The FIMC-LITE and MIPI-CSIS drivers can also be reused in the Exynos5
SoC series.

0f735f5236 [media] s5p-fimc: Rework the video pipeline control functions
There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.

Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.

struct fimc_pipeline declaration is moved to the driver's public header
to allow other drivers to reuse the fimc-lite driver added in subsequent
patches.

693f5c4082 [media] s5p-fimc: Use v4l2_subdev internal ops to register video nodes
In order to be able to select only FIMC-LITE support, which is added
with subsequent patches, the regular FIMC support is now contained
only in fimc-core.c, fimc-m2m.c and fimc-capture.c files. The graph
and pipeline management is now solely handled in fimc-mdevice.[ch].
This means the FIMC driver can now be excluded with Kconfig option,
leaving only FIMC-LITE and allowing this driver to be reused in SoCs
that have only FIMC-LITE and no regular FIMC IP.

41df5bf088 [media] s5p-fimc: Avoid crash with null platform_data
In commit "s5p-fimc: Handle sub-device interdependencies using deferred.."
there was a check added for pdata->num_clients without first checking
pdata against NULL. This causes a crash when platform_data is not set,
which is a valid use case. Fix this regression by skipping the MIPI-CSIS
subdev registration also when pdata is null.

fec0f72f5f [media] V4L: sh_mobile_ceu_camera: don't fail TRY_FMT
VIDIOC_TRY_FMT shouldn't fail if the user requests an unsupported pixel
format. Instead the driver should replace it with a supported one. Fix the
sh_mobile_ceu_camera driver accordingly.

9633c0867f [media] V4L: soc-camera: switch to using the existing .enum_framesizes()
The recently introduced .enum_mbus_fsizes() v4l2-subdev video operation is
a duplicate of the .enum_framesizes() operation, introduced earlier. Switch
soc-camera over to using the original one.

67e86524b9 [media] V4L: mx2-camera: avoid overflowing 32-bits
In mx2_camera_try_fmt(), when applying i.MX25 restrictions to frame sizes,
the height is checked to be <= 0xffff. But later an integer multiplication
height * 4 * 0x3ffff is performed, which will overflow even for bounded
height values. This patch switches to using 64-bit multiplication and
division to avoid overflowing.

914f05c811 [media] soc-camera: Support user-configurable line stride
Add a capabilities field to the soc_camera_host structure to flag hosts
that support user-configurable line strides. soc_camera_try_fmt() then
passes the user-provided bytesperline and sizeimage format fields to
such hosts, and expects the host to check (and fix if needed) the
values.
