Pull i2c changes from Wolfram Sang:
- an arbitration driver. While the driver is quite simple, it caused
discussion if we need additional arbitration on top of the one
specified in the I2C standard. Conclusion is that I accept a few
generic mechanisms, but not very specific ones.
- the core lost the detach_adapter() call. It has no users anymore and
was in the way for other cleanups. attach_adapter() is sadly still
there since there are users waiting to be converted.
- the core gained a bus recovery infrastructure. I2C defines a way to
recover if the data line is stalled. This mechanism is now in the
core and drivers can now pass some data to make use of it.
- bigger driver cleanups for designware, s3c2410
- removing superfluous refcounting from drivers
- removing Ben Dooks as second maintainer due to inactivity. Thanks
for all your work so far, Ben!
- bugfixes, feature additions, devicetree fixups, simplifications...

i2c_del_adapter() always returns 0. So all checks testing whether it will be
non zero will always evaluate to false and the conditional code is dead code.
This patch updates all callers of i2c_del_mux_adapter() to ignore the return
value and assume that it will always succeed (which it will). In a subsequent
patch the return type of i2c_del_adapter() will be made void.

Loading the cypress firmware is not dvb specific and should be common
functionality. Move the source to media/common and make it a standalone
module.
As a result we can remove the dependency on dvb-usb in go7007, which has
nothing to do with dvb.

The go7007 driver would continue during probe if no firmware could be
loaded. Without firmware the probe() should return an error, so do that.
Also move the registration of devices to the end of the probe() sequence:
once devices appear the full driver functionality should be available.

The go7007 produces elementary streams, so we shouldn't use the STREAM_TYPE
control, since that is for multiplexed streams.
Instead use V4L2_PIX_FMT_MPEG1/2/4.
Initially set up all the values for MPEG-2 dvd-mode, and select the dvd_mode
field if those values match that setup precisely.
Clean up lots of obsolete code relating to the custom ioctls for the MPEG
support.

- The Adlink is initially detected as a sensor board, so the driver config
is set up as if it was a sensor. Later the driver discovers that it really
is a video capture card and that means that the driver configuration has
to be updated for a PAL/NTSC capture card.
- Setup the correct initial std based on the TV tuner type.
- Remember the exact std the user selected, don't map it to STD_PAL or NTSC.
- Use v4l2_disable_ioctl to disable ioctls based on the board config and
drop a lot of checking code in each of those ioctls since that is no longer
needed.
- enum_input should use tvnorms to fill its std field.
- configure the input, std and initial tuner frequency at driver initialization.
- fix std handling in the s2250 driver.
- the code handling scaling for devices without a scaler was broken. This is
now fixed.
- correctly set readbuffers and capability in g/s_parm.
- remove the bogus test for capturemode in s_parm.
- correctly implement enum_framesizes/intervals.

- use the v4l2_device's release() callback
- remove the unnecessary ref_count

Instead of using the wis-* drivers we now use the standard 'proper' subdev
drivers.
The board configuration tables now also list the possible audio inputs,
this will be used later to implement audio inputs.
Special mention deserves a little change in set_capture_size() where the
height passed to s_mbus_fmt is doubled: that is because the saa7115 driver
expects to see the frame height, not the field height as the wis_saa7115
driver did.
Another change is that the tuner input is moved from last to the first
input, which is consistent with the common practice in other video drivers.

This adds support for three Sony BTF tuners:
TUNER_SONY_BTF_PG472Z: PAL+SECAM
TUNER_SONY_BTF_PK467Z: NTSC-M-JP
TUNER_SONY_BTF_PB463Z: NTSC-M
These come from the go7007 staging driver where they were implemented in
the wis-sony-tuner i2c driver.
Adding support for these tuners to tuner-types.c is the first step towards
