[media] vivid: add the kthread code that controls the video rate
Add the kthread handlers for video/vbi capture and video/vbi output.
These carefully control the rate at which frames are generated (video
capture) and accepted (video output). While the short-term jitter is
around the order of a jiffie, in the long term the rate matches the
configured framerate exactly.
The capture thread handler also takes care of the video looping and
of capture and overlay support. This is probably the most complex part
of this driver due to the many combinations of crop, compose and scaling
on the input and output, and the blending that has to be done if
overlay support is enabled as well.

[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).
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.

[media] sp2: Add I2C driver for CIMaX SP2 common interface module
Driver for the CIMaX SP2 common interface chip. It is very much based on
the existing cimax2 driver for cx23885, but should be more reusable. The
product has been sold with name Atmel T90FJR as well and the data sheets
for that chip seem to be publicly available.
It seems that the USB device that I have and the cx23885 based devices will
need to interact differently with the chip for the CAM operations. Thus
there is one callback function that is passed on to the sp2 driver
(see function sp2_ci_op_cam for that one).
IRQ functionality is not included currently (not needed by USB devices
and I don't have a PCIe device for development).

[media] si2168: add ts_mode setting and move to si2168_init
Luis Alves submitted a TS mode patch to si2168 earlier, but the
patch was rejected due to a small issue. Here is a working version.
Also, setting of TS mode is moved from si2168_set_frontend to
si2168_init.
This patch adds the TS mode as a config option for the si2168 demod:
- ts_mode added to config struct.
- Possible (interesting) values are
* Parallel mode = 0x06
* Serial mode = 0x03
Currently the modules using this demod only use parallel mode.
Patches for these modules later in this patch series.

[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:

There are several arch-specific media drivers that don't
require asm-specific includes and can be successfully
compiled on x86. Add COMPILE_TEST dependency for them, in
order to allow a broader test on those drivers.
That helps static analysis tools like Coverity to discover
eventual troubles there.
That helps some static checks, so enable it. While there, it was
noticed that linux/sizes.h was missing:
