e74d7e6d34 [media] bttv: remove g/s_audio since there is only one audio input
Note that the current driver does not implement enumaudio (so apps cannot
tell that audio inputs are present), it does not set V4L2_CAP_AUDIO, nor
does it set audioset when calling ENUM_INPUT. And G_AUDIO doesn't set the
stereo flag either. So these g/s_audio ioctls are quite pointless and
misleading. Especially since some surveillance boards do not have audio
at all.

b8e2a361ce [media] bttv: do not switch to the radio tuner unless it is accessed
Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on
automatically.

385cd33c8d [media] em28xx-dvb: Don't put device in suspend mode at feed stop
Putting em28xx in suspend mode when a feed stops is just plain
wrong. Every time a new PES filter is changed, the DVB demux
code will stop the current feed, and then start a new one.
If are there any code that switches off the frontend, via
some GPIO setting, this would make the DVB fail.
This condition was actually trigged with one device, during
DVB scan, as, during scan, it is common that userspace apps
to change the filter several times, in order to get all
tables.
Also, this is not needed at all, since the em28xx code already
hooks into ops.ts_bus_ctrl(). This warrants that em28xx can
check there if DVB frontend is in usage or not. The code there
already puts the device on suspend mode, if the DVB frontend
is not used (closed).

is out of the recommended range. So, let's stick with the
default.
With regards to the IF voltage level, instead of using
0.5 V(p-p) for IF, use 2V, giving a 12dB gain.
The rationale is that, on PixelView SBTVD Hybrid,
even 2V(p-p) would be in the nominal range for IF,
as the maximum range on this particular device is 3V.
A higher gain here should help to improve reception under
weak signals.

a78b41d5fd [media] mb86a20s: Always reset the frontend with set_frontend
Always init the frontend when set_frontend is called. The rationale
is: it was noticed that, on some devices, it fails to lock with a
different channel. It seems that some other registers need to be
restored to its initial state, when the channel changes.
As it is better to reset everything, even wasting a few more
miliseconds than to loose channel lock, let's change the logic
to always reset.

15b1c5a068 [media] mb86a20s: provide CNR stats before FE_HAS_SYNC
State 9 means TS started to be output, and it should be
associated with FE_HAS_SYNC.
The mb86a20scan get CNR statistics at state 7, when frame sync
is obtained.
As CNR may help to adjust the antenna, provide it earlier.
A latter patch could eventually start outputing MER measures
earlier, but that would require a bigger change, and probably
won't be better than the current way, as the time between
changing from state 8 to 9 is generally lower than the time
to get the stats collected.

510e884c1a [media] em28xx: extract the device configuration dataset from eeproms with 16 bit address width
The new eeproms with 16 address width still have the the device config dataset
(the content of the old 8 bit eeproms) embedded.
Hauppauge also continues to include the tveeprom data structure inside this
dataset in their devices.
The start address of the dataset depends on the start address of the microcode
and a variable additional offset.
It should be mentioned that Camera devices seem to use a different dataset type,
which is not yet supported.
Tested with devices "Hauppauge HVR-930C". I've also checked the USB-log from the
"MSI Digivox ATSC" and it works the same way.

a217968f91 [media] em28xx: do not store eeprom content permanently
We currently reserve an array of 256 bytes for the eeprom content in the device
struct. For eeproms with 16 bit address width it might even be necessary to
increase the buffer size further.
Having such a big chunk of memory reserved even if the device has no eeprom and
keeping it after it has already been processed seems to be a waste of memory.
Change the code to allocate + free the eeprom memory dynamically.
This also makes it possible to handle different dataset sizes depending on what
is stored/found in the eeprom.

87b52439cf [media] em28xx: add basic support for eeproms with 16 bit address width
Newer devices (em2874, em2884, em28174, em25xx, em27[6,7,8]x) use eeproms with
16 bit instead of 8 bit address width.
The used eeprom type depends on the chip type, which makes sure eeproms can't
be damaged.
This patch adds basic support for 16 bit eeproms only, which includes
- reading the content
- calculating the eeprom hash
- displaying the content
The eeprom content uses a different format, for which support will be added with
subsequent patches.
Tested with the "Hauppauge HVR-930C" and the "Speedlink VAD Laplace webcam"
(with additional experimental patches).

The em28xx driver has changed much, especially since kernel 3.8.
So it's time to bump the driver version.
Changes since kernel 3.8:
- converted the driver to videobuf2
- converted the driver to the v4l2-ctrl framework
- added USB bulk transfer support
- use USB bulk transfers by default for webcams (allows streaming from multiple devices at the same time)
- added image quality bridge controls: contrast, brightness, saturation, blue balance, red balance, sharpness
- removed dependency from module ir-kbd-i2c
- cleaned up the frame data processing code
- removed some unused/obsolete code
- made remote controls of devices with external (i2c) receiver/decoder work again
- fixed audio over USB for device "Terratec Cinergy 250"
- several v4l2 compliance fixes and improvements (including fixes for ioctls enabling/disabling)
- lots of further bug fixes and code improvements

3298a3511f arm-soc: multiplatform support
Converting more ARM platforms to multiplatform support. This time, OMAP
 gets converted, which is a major step since this is by far the largest
 platform in terms of code size. The same thing happens to the vt8500
 platform.
 
 Conflicts include:
 * Two mach/uncompress.h files are removed, the changes made to them
   elsewhere can be discarded now.
 * Moving the OMAP4 irq_match array has context clashes with turning
   omap4_sar_ram_init into an omap_early_initcall()

ac89758697 Revert "[media] dvb_frontend: return -ENOTTY for unimplement IOCTL"
As reported by Klaus Schmidinger:
 "In VDR I use an ioctl() call with FE_READ_UNCORRECTED_BLOCKS on a
  device (using stb0899).  After this call I check 'errno' for
  EOPNOTSUPP to determine whether this device supports this call.  This
  used to work just fine, until a few months ago I noticed that my
  devices using stb0899 didn't display their signal quality in VDR's OSD
  any more.  After further investigation I found that
  ioctl(FE_READ_UNCORRECTED_BLOCKS) no longer returns EOPNOTSUPP, but
  rather ENOTTY.  And since I stop getting the signal quality in case
  any unknown errno value appears, this broke my signal quality query
  function."

While the changes reflect what is there at:

  http://comments.gmane.org/gmane.linux.kernel/1235728

it does cause regression on userspace.  So, revert it to stop the
damage.

Merge branch 'omap/multiplatform-fixes', tag 'v3.8-rc5' into next/multiplatform

The omap multiplatform support uncovered a bug in the cwdavinci_cpdma
code and was missing two drivers that are enabled now but are not
quite ready for multiplatform, as found by allyesconfig builds.

There is also a conflict generated by automated merge in
arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5
and a different version of the same fix that went into the
omap/multiplatform branch. This merge removes the extraneous
 #include that was causing build errors.

It is now possible to build the davinci vpss code
on multiplatform kernels, which causes a problem
since the driver tries to incude the davinci
platform specific mach/hardware.h file. Fortunately
that file is not required at all in the driver,
so we can simply remove the #include statement.

Without this patch, building allyesconfig results in:

ed72d37a33 [media] media: Add 0x3009 USB PID to ttusb2 driver (fixed diff)
The "Technisat SkyStar USB plus" is a TT-connect S-2400 clone, which the
V4L-DVB drivers already support. However, some of these devices (like
mine) come with a different USB PID 0x3009 instead of 0x3006.

There have already been patches simply overwriting the USB PID in
dvb-usb-ids.h. Of course these patches were rejected because they would
have disabled the 0x3006 PID.

This new patch adds the 0x3009 PID to dvb-usb-ids.h, and adds references
to it within the ttusb2.c driver. PID 0x3006 devices will continue to work.

The only difference between the two hardware models seems to be the
EEPROM chip. In fact, Windows BDA driver names the 0x3009 device with a
"(8 kB EEPROM)" suffix. In spite of that, the 0x3009 device works
absolutely flawlessly using the existing ttusb2 driver.

This patch adds device tree parsing for gpio_ir_recv platform_data and
the mandatory binding documentation. It basically follows what we already
have for e.g. gpio_keys. All required device tree properties are OS
independent but an optional property allows linux specific support for rc
maps.

The original commit, adding the mt9t112 driver said, that mt9t111 and
mt9t112 had identical register layouts. This however doesn't seem to be
the case. At least pixel format selection in the mt9t111 datasheet is
different from the driver implementation. So far only the default YUYV
format has been verified to work with mt9t111. Limit the driver to only
report one supported format with mt9t111 until more formats are

these functions are called *after* initialization by the main cx18/ivtv

33f6984ece [media] em28xx: fix analog streaming with USB bulk transfers
With the conversion to videobuf2, some unnecessary calls of
em28xx_set_alternate() have been removed. It is now called at analog streaming
start only.
This has unveiled a bug that causes USB bulk transfers to fail with all urbs
having status -EVOERFLOW.
The reason is, that for bulk transfers usb_set_interface() needs to be called
even if the previous alt setting was the same (side note: bulk transfers seem
to work only with alt=0).
While it seems to be NOT necessary for isoc transfers, it's reasonable to just
call usb_set_interface() unconditionally in em28xx_set_alternate().
Also add a comment that explains the issue to prevent regressions in the future.

bf5bbed15c [media] dvb-usb: check for invalid length in ttusb_process_muxpack()
This patch is driven by a static checker warning.
The ttusb_process_muxpack() function is only called from
ttusb_process_frame().  Before calling, it verifies that len >= 2.  The
problem is that len == 2 is not valid and would lead to an array
underflow.
Odd number values for len are also invalid and would lead to reading
past the end of the array.
