ca42129f86 [media] dvb-usb-v2: add frontend_detach callback
Add frontend_detach callback in order to allow custom detach. It is
needed when demod driver is implemented I2C client or some other
kernel bus, but not proprietary dvb_attach / dvb_detach.

to do the binding.

6832d11edd [media] cxusb: Add support for TechnoTrend TT-connect CT2-4650 CI
TechnoTrend TT-connect CT2-4650 CI (0b48:3012) is an USB DVB-T2/C tuner with
the following components:

 USB interface: Cypress CY7C68013A-56LTXC
 Demodulator: Silicon Labs Si2168-A20
 Tuner: Silicon Labs Si2158-A20
 CI chip: CIMaX SP2HF

The firmware for the tuner is the same as for TechnoTrend TT-TVStick CT2-4400.
See https://www.mail-archive.com/linux-media@vger.kernel.org/msg76944.html

The demodulator needs a firmware that can be extracted from the Windows drivers.
File ttConnect4650_64.sys should be extracted from
http://www.tt-downloads.de/bda-treiber_4.1.0.4.zip (MD5 sum below).

3464bfc37a47b4032568718bacba23fb  ttConnect4650_64.sys

Then the firmware can be extracted:
dd if=ttConnect4650_64.sys ibs=1 skip=273376 count=6424 of=dvb-demod-si2168-a20-01.fw

The SP2 CI module requires a definition of a function cxusb_tt_ct2_4650_ci_ctrl
that is passed on to the SP2 driver and called back for CAM operations.

7a0af6ed97 [media] media: fix kernel deadlock due to tuner pull-out while playing
Normally, ADAP_STREAMING bit is set in dvb_usb_start_feed and cleared in
dvb_usb_stop_feed.

But in exceptional cases, for example, when the tv is playing programs
and the tuner is pulled out, then dvb_usbv2_disconnect is called.

In such case, it will first call dvb_usbv2_adapter_frontend_exit to stop
dvb_frontend_thread, and then call dvb_usbv2_adapter_dvb_exit to clear
ADAP_STREAMING bit.

At this point, if dvb_frontend_thread is sleeping and waiting for
ADAP_STREAMING to be cleared to get out of sleep. then
dvb_frontend_thread can never be stoped, because clearing ADAP_STREAMING
bit is performed after dvb_frontend_thread is stopped (i.e. performed in
dvb_usbv2_adapter_dvb_exit).

So, deadlock:

627530c32a [media] em28xx-v4l: give back all active video buffers to the vb2 core properly on streaming stop
When a new video frame is started, the driver takes the next video buffer from
the list of active buffers and moves it to dev->usb_ctl.vid_buf / dev->usb_ctl.vbi_buf
for further processing.

On streaming stop we currently only give back the pending buffers from the list
but not the ones which are currently processed.

This causes the following warning from the vb2 core since kernel 3.15:

2930977ac5 [media] au0828: Fix DVB resume when streaming
When DVB is streaming and suspend is called, it will call
au0828_stop_transport(), with will clean the streaming flag.

Due to that, stop_urb_transfer() will be called twice,
causing an oops.

So, we need another flag to be used at resume, telling it
to restart DVB.

While here, add a logic at stop_urb_transfer() to prevent
it of being called twice, and convert the usb_streaming
flag into boolean.

dev->dvb is always not null, as it is an area at the dev
memory. So, checking if (dev->dvb) is always true.

Instead of this stupid check, what the code wants to do is
to know if the DVB was successully registered.

Fix it by checking, instead, for dvb->frontend. It should
also be sure that this var will be NULL if the device was
not properly initialized.

2e0cc7ee75 [media] au0828-input: Be sure that IR is enabled at polling
When the DVB code sets the frontend, it disables the IR
INT, probably due to some hardware bug, as there's no code
there at au8522 frontend that writes on register 0xe0.

Fixing it at au8522 code is hard, as it doesn't know if the
IR is enabled or disabled, and just restoring the value of
register 0xe0 could cause other nasty effects. So, better
to add a hack at au0828-input polling interval to enable int,
if disabled.

cfd0c77d08 [media] au0828: improve I2C speed
Commits 21dc61d3c0 and 7a1dd50b89 reduced the board I2C
speed to 20 MHz by default, due to a I2C stretch issue:
while xc5000 uses i2c stretch when a command is sent to it,
au0828 doesn't support this feature.

However, this is needed only for Xceive tuners. The other
I2C devices can work at the max speed.

So, revert the workarounds at board level, handling it at
I2C level, only when talking with xc5000.
