Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media into next 

Pull media updates from Mauro Carvalho Chehab:
 "This contains:
   - a new frontend/tuner driver set for si2168 and sa2157
   - Videobuf 2 core now supports DVB too
   - A new gspca sub-driver (dtcs033)
   - saa7134 is now converted to use videobuf2
   - add support for 4K timings
   - several other driver fixes and improvements

  PS.  This pull request is shorter than usual, partly because I have
  some other patches on topic branches that I'll be sending you later
  this week"

<para>This event is triggered when a source parameter change is
detected during runtime by the video device. It can be a
runtime resolution change triggered by a video decoder or the
format change happening on an input connector.
This event requires that the <structfield>id</structfield>
matches the input index (when used with a video device node)
or the pad index (when used with a subdevice node) from which
you want to receive events.</para>
<para>This event has a &v4l2-event-src-change; associated
with it. The <structfield>changes</structfield> bitfield denotes
what has changed for the subscribed pad. If multiple events
occurred before application could dequeue them, then the changes
will have the ORed value of all the events generated.</para>

6. Platform support
===================
The machine code (arch/arm/plat-samsung and arch/arm/mach-*) must select
following options:
CONFIG_S5P_DEV_FIMC0 mandatory
CONFIG_S5P_DEV_FIMC1 \
CONFIG_S5P_DEV_FIMC2 | optional
CONFIG_S5P_DEV_FIMC3 |
CONFIG_S5P_SETUP_FIMC /
CONFIG_S5P_DEV_CSIS0 \ optional for MIPI-CSI interface
CONFIG_S5P_DEV_CSIS1 /
Except that, relevant s5p_device_fimc? should be registered in the machine code
in addition to a "s5p-fimc-md" platform device to which the media device driver
is bound. The "s5p-fimc-md" device instance is required even if only mem-to-mem
operation is used.
The description of sensor(s) attached to FIMC/MIPI-CSIS camera inputs should be
passed as the "s5p-fimc-md" device platform_data. The platform data structure
is defined in file include/media/s5p_fimc.h.
7. Build
========
This driver depends on following config options:
PLAT_S5P,
PM_RUNTIME,
I2C,
REGULATOR,
VIDEO_V4L2_SUBDEV_API,
If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
optional s5p-csis.ko (MIPI-CSI receiver subdev).
