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).

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.

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:

au0828 doesn't resume correctly and TV tuning fails with
xc_set_signal_source(0) failed message. Change au0828 dvb
suspend and resume interfaces to suspend and resume frontend
during suspend and resume respectively. dvb_frontend_suspend()
suspends tuner and fe using tuner and fe ops. dvb_frontend_resume()
resumes fe and tuner using fe and tuner ops ini before waking up
the frontend. With this change HVR950Q suspend and resume work
when system gets suspended when digital function is tuned to a
channel and with active TV stream, and after resume it went right
back to active TV stream.

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:

this long standing issue and who has investigated it further.
