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."

<ulink url="http://en.wikipedia.org/wiki/Digital_Visual_Interface">DVI</ulink>
(Digital Visual Interface), HDMI (<xref linkend="hdmi" />) and DisplayPort (<xref linkend="dp" />).
These controls are generally expected to be private to the receiver or transmitter
subdevice that implements them, so they are only exposed on the
<filename>/dev/v4l-subdev*</filename> device node.
</para>
<para>Note that these devices can have multiple input or output pads which are
hooked up to e.g. HDMI connectors. Even though the subdevice will receive or
transmit video from/to only one of those pads, the other pads can still be
active when it comes to EDID (Extended Display Identification Data,
<xref linkend="vesaedid" />) and HDCP (High-bandwidth Digital Content
Protection System, <xref linkend="hdcp" />) processing, allowing the device
to do the fairly slow EDID/HDCP handling in advance. This allows for quick
switching between connectors.</para>
<para>These pads appear in several of the controls in this section as
bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad 1,
etc. The maximum value of the control is the set of valid pads.</para>

<para>This is a multi-planar format, as opposed to a packed format.
The three components are separated into three sub-images or planes.
The Y plane is first. The Y plane has one byte per pixel. The Cr data
constitutes the second plane which is half the width and half
the height of the Y plane (and of the image). Each Cr belongs to four
pixels, a two-by-two square of the image. For example,
Cr<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
Y'<subscript>01</subscript>, Y'<subscript>10</subscript>, and
Y'<subscript>11</subscript>. The Cb data, just like the Cr plane, constitutes
the third plane. </para>
<para>If the Y plane has pad bytes after each row, then the Cr
and Cb planes have half as many pad bytes after their rows. In other
words, two Cx rows (including padding) is exactly as long as one Y row
(including padding).</para>
<para><constant>V4L2_PIX_FMT_YVU420M</constant> is intended to be
used only in drivers and applications that support the multi-planar API,

API lacks any support for composing to and cropping from an image inside a
memory buffer. The application could configure a capture device to fill only a
part of an image by abusing V4L2 API. Cropping a smaller image from a larger
one is achieved by setting the field <structfield>
&v4l2-pix-format;::bytesperline </structfield>. Introducing an image offsets
could be done by modifying field <structfield> &v4l2-buffer;::m:userptr

could be done by modifying field &v4l2-buffer;<structfield>::m_userptr</structfield>
before calling <constant> VIDIOC_QBUF </constant>. Those
operations should be avoided because they are not portable (endianness), and do
not work for macroblock and Bayer formats and mmap buffers. The selection API
deals with configuration of buffer cropping/composing in a clear, intuitive and
portable way. Next, with the selection API the concepts of the padded target
and constraints flags are introduced. Finally, <structname> &v4l2-crop;
</structname> and <structname> &v4l2-cropcap; </structname> have no reserved
fields. Therefore there is no way to extend their functionality. The new
<structname> &v4l2-selection; </structname> provides a lot of place for future

The new &v4l2-selection; provides a lot of place for future
extensions. Driver developers are encouraged to implement only selection API.
The former cropping API would be simulated using the new one. </para>

<title>Description</title>
<para>These ioctls can be used to get or set an EDID associated with an input pad
from a receiver or an output pad of a transmitter subdevice.</para>
<para>To get the EDID data the application has to fill in the <structfield>pad</structfield>,
<structfield>start_block</structfield>, <structfield>blocks</structfield> and <structfield>edid</structfield>
fields and call <constant>VIDIOC_SUBDEV_G_EDID</constant>. The current EDID from block
<structfield>start_block</structfield> and of size <structfield>blocks</structfield>
will be placed in the memory <structfield>edid</structfield> points to. The <structfield>edid</structfield>
pointer must point to memory at least <structfield>blocks</structfield>&nbsp;*&nbsp;128 bytes
large (the size of one block is 128 bytes).</para>
<para>If there are fewer blocks than specified, then the driver will set <structfield>blocks</structfield>
to the actual number of blocks. If there are no EDID blocks available at all, then the error code
ENODATA is set.</para>
<para>If blocks have to be retrieved from the sink, then this call will block until they
have been read.</para>
<para>To set the EDID blocks of a receiver the application has to fill in the <structfield>pad</structfield>,
<structfield>blocks</structfield> and <structfield>edid</structfield> fields and set
<structfield>start_block</structfield> to 0. It is not possible to set part of an EDID,
it is always all or nothing. Setting the EDID data is only valid for receivers as it makes
no sense for a transmitter.</para>
<para>The driver assumes that the full EDID is passed in. If there are more EDID blocks than
the hardware can handle then the EDID is not written, but instead the error code E2BIG is set
and <structfield>blocks</structfield> is set to the maximum that the hardware supports.
If <structfield>start_block</structfield> is any
value other than 0 then the error code EINVAL is set.</para>
<para>To disable an EDID you set <structfield>blocks</structfield> to 0. Depending on the
hardware this will drive the hotplug pin low and/or block the source from reading the EDID
data in some way. In any case, the end result is the same: the EDID is no longer available.

By default, a TV driver auto-selects all possible tuners
thar could be used by the driver.
This is generally the right thing to do, except when there
are strict constraints with regards to the kernel size.
Use this option with care, as deselecting tuner drivers which
are in fact necessary will result in TV devices which cannot
be tuned due to lack of the tuning driver.
If unsure say Y.
