[Patch 0/7] Add em28xx driver from mcentral.de

[Markus Rechberger]

I got adviced to submit the drivers independently.
this patch adds support for all outstanding em28xx devices which are
currently supported on mcentral.de (at least 40 devices).

a small summary:
* adding VBI support to em28xx based devices (for tvp5150 based
devices this depends on a recently submitted patch to linuxtv.org)
* stereo FM radio support for cx25843 based devices
* extra cx25843 driver (registers match the em28xx configuration in
order to support proper VBI)
* all videostandards and inputs are tested with cx25843 based devices,
successful firmware reloading after switching back from a certain mode
* adding alternative audio driver for em28xx devices (independent
audio transfer, not depending on oss/alsa)
* adding em28xx-webcam support for videology webcams
* adding em28xx-audioep audio driver for alternate number 1 - if
vendor specific and not USB audio conform
* adding sharp s921 chip driver (ISDB-T 1Seg support tunneling
parameters through DVB-T API setting specific registers to auto)
* adding xc3028 mostly original sourcecode from the manufacturer (most
recent version), merged xc3028/xc3028l into
  one external firmware blob - important for signal quality
* adding xc5000 mostly original sourcecode from the manufacturer (most
recent version) - important for signal quality
* adding lgdt3304, although currently not used
* remote control handling *works* but is broken by design and disabled
since different rc5/rc6/nec remotes return
  different values. Handling can be done using interrupt transfers too (TODO)
* adding support for em2888 based devices (analog TV/digital TV/flash)
