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

Pull media updates from Mauro Carvalho Chehab:
 "The first part of the media updates for Kernel 3.7.

  This series contain:

   - A major tree renaming patch series: now, drivers are organized
     internally by their used bus, instead of by V4L2 and/or DVB API,
     providing a cleaner driver location for hybrid drivers that
     implement both APIs, and allowing to cleanup the Kconfig items and
     make them more intuitive for the end user;

   - Media Kernel developers are typically very lazy with their duties
     of keeping the MAINTAINERS entries for their drivers updated.  As
     now the tree is more organized, we're doing an effort to add/update
     those entries for the drivers that aren't currently orphan;

   - Several DVB USB drivers got moved to a new DVB USB v2 core; the new
     core fixes several bugs (as the existing one that got bitroted).
     Now, suspend/resume finally started to work fine (at least with
     some devices - we should expect more work with regards to it);

   - added multistream support for DVB-T2, and unified the API for
     DVB-S2 and ISDB-S.  Backward binary support is preserved;

   - as usual, a few new drivers, some V4L2 core improvements and lots
     of drivers improvements and fixes.

  There are some points to notice on this series:

   1) you should expect a trivial merge conflict on your tree, with the
      removal of Documentation/feature-removal-schedule.txt: this series
      would be adding two additional entries there.  I opted to not
      rebase it due to this recent change;

   2) With regards to the PCTV 520e udev-related breakage, I opted to
      fix it in a way that the patches can be backported to 3.5 even
      without your firmware fix patch.  This way, Greg doesn't need to
      rush backporting your patch (as there are still the firmware cache
      and firmware path customization issues to be addressed there).

      I'll send later a patch (likely after the end of the merge window)
      reverting the rest of the DRX-K async firmware request, fully
      restoring its original behaviour to allow media drivers to
      initialize everything serialized as before for 3.7 and upper.

   3) I'm planning to work on this weekend to test the DMABUF patches
      for V4L2.  The patches are on my queue for several Kernel cycles,
      but, up to now, there is/was no way to test the series locally.

      I have some concerns about this particular changeset with regards
      to security issues, and with regards to the replacement of the old
      VIDIOC_OVERLAY ioctl's that is broken on modern systems, due to
      GPU drivers change.  The Overlay API allows direct PCI2PCI
      transfers from a media capture card into the GPU framebuffer, but
      its API is crappy.  Also, the only existing X11 driver that
      implements it requires a XV extension that is not available
      anymore on modern drivers.  The DMABUF can do the same thing, but
      with it is promising to be a properly-designed API.  If I can
      successfully test this series and be happy with it, I should be
      asking you to pull them next week."

-SUPPORTED HARDWARE
-------------------
-
-This driver is intended for use with hardware having USB ID 05e1:0408.
-Two kinds of EasyCAP have this USB ID, namely:
-
-    *  EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
-       having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
-
-    *  EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
-       1, 2, 3, 4 and an unlabelled input cable for a microphone.
-
-
-BUILD OPTIONS AND DEPENDENCIES
-------------------------------
-
-Unless EASYCAP_DEBUG is defined during compilation it will not be possible
-to select a debug level at the time of module installation.
-
-
-KNOWN RUNTIME ISSUES
---------------------
-
-(1) Intentionally, this driver will not stream material which is unambiguously
-identified by the hardware as copy-protected.  Normal video output will be
-present for about a minute but will then freeze when this situation arises.
-
-(2) The controls for luminance, contrast, saturation, hue and volume may not
-always work properly.
-
-(3) Reduced-resolution S-Video seems to suffer from moire artefacts.
-
-
-INPUT NUMBERING
----------------
-
-For the EasyCAP with S-VIDEO input cable the driver regards a request for
-inputs numbered 0 or 1 as referring to CVBS and a request for input
-numbered 5 as referring to S-VIDEO.
-
-For the EasyCAP with four CVBS inputs the driver expects to be asked for
-any one of inputs numbered 1,2,3,4.  If input 0 is asked for, it is
-interpreted as input 1.
-
-
-MODULE PARAMETERS
------------------
-
-Three module parameters are defined:
-
-debug      the easycap module is configured at diagnostic level n (0 to 9)
-gain       audio gain level n (0 to 31, default is 16)
-bars       whether to display testcard bars when incoming video signal is lost
-           0 => no, 1 => yes (default)
-
-
-SUPPORTED TV STANDARDS AND RESOLUTIONS
---------------------------------------
-
-The following TV standards are natively supported by the hardware and are
-usable as (for example) the "norm=" parameter in the mplayer command:
-
-    PAL_BGHIN,    NTSC_N_443,
-    PAL_Nc,       NTSC_N,
-    SECAM,        NTSC_M,        NTSC_M_JP,
-    PAL_60,       NTSC_443,
-    PAL_M.
-
-In addition, the driver offers "custom" pseudo-standards with a framerate
-which is 20% of the usual framerate.  These pseudo-standards are named:
-
-    PAL_BGHIN_SLOW,    NTSC_N_443_SLOW,
-    PAL_Nc_SLOW,       NTSC_N_SLOW,
-    SECAM_SLOW,        NTSC_M_SLOW,        NTSC_M_JP_SLOW,
-    PAL_60_SLOW,       NTSC_443_SLOW,
-    PAL_M_SLOW.
-
-
-The available picture sizes are:
-
-     at 25 frames per second:   720x576, 704x576, 640x480, 360x288, 320x240;
-     at 30 frames per second:   720x480, 640x480, 360x240, 320x240.
-
-
-WHAT'S TESTED AND WHAT'S NOT
-----------------------------
-
-This driver is known to work with mplayer, mencoder, tvtime, zoneminder,
-xawtv, gstreamer and sufficiently recent versions of vlc.  An interface
-to ffmpeg is implemented, but serious audio-video synchronization problems
-remain.
-
-The driver is designed to support all the TV standards accepted by the
-hardware, but as yet it has actually been tested on only a few of these.
-
-I have been unable to test and calibrate the S-video input myself because I
-do not possess any equipment with S-video output.
-
-
-UDEV RULES
-----------
-
-In order that the special files /dev/easycap0 and /dev/easysnd1 are created
-with conveniently relaxed permissions when the EasyCAP is plugged in, a file
-is preferably to be provided in directory /etc/udev/rules.d with content:
-
-ACTION!="add|change", GOTO="easycap_rules_end"
-ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
-	MODE="0666", OWNER="root", GROUP="root"
-LABEL="easycap_rules_end"
-
-
-MODPROBE CONFIGURATION
-----------------------
-
-The easycap module is in competition with the module snd-usb-audio for the
-EasyCAP's audio channel, and its installation can be aided by providing a
-file in directory /etc/modprobe.d with content:
-
-options easycap  gain=16 bars=1
-install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap
-
-
-ACKNOWLEGEMENTS AND REFERENCES
-------------------------------
-This driver makes use of information contained in the Syntek Semicon DC-1125
-Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
-by Nicolas Vivien.  Particularly useful has been a patch to the latter driver
-provided by Ivor Hewitt in January 2009.  The NTSC implementation is taken
-from the work of Ben Trask.
