Following patch adds the latest em28xx driver from mcentral.de.
merging mcentral.de/hg/~mrec/em28xx-new with upstream kernel
* adding VBI support to most VBI capable devices
* 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
* 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 s921 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 disabled
* 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)
* fixed a couple of bugs in the em28xx-audio driver which can lead to
system hangs.
----
as for testing:
* analog TV: patched tvtime (for analog TV) version available on
mcentral.de which supports 1. software rendering 2. digital
audio/alsa/aad
* FM radio: gqradio from mcentral.de, there's also an older radio
patch for vlc available.
* DVB-T: all applications should work with it
* ISDB-T: relevant for China and Brazil only, can be used with
dvbtune, dvbscan (the channel file cannot be used due problems with
the characters), for transferring the MPEG-TS stream dvbstream,
dvbsnoop, for playback gstreamer/mplayer (h264/aac isn't supported
well with it).

There is already an Empia EM28XX driver in the official tree. If your driver
is based on it, could you point at the first commit in *your* tree at
mcentral.de which
corresponds to that driver? (if you do, your history can be moved into
central Git
repo completely, every commit of it)

The development has been split off for 3 years from the original
repository. The internal driver differs alot.
The full history of that driver can be seen when looking at:
http://mcentral.de/hg/~mrec/v4l-dvb-experimental
that code back then got split out of the linuxtv repository and moved to:
http://mcentral.de/hg/~mrec/em28xx-new
The driver has a long and rather bad history, which I'd like to avoid
by using the different directory.
Some patches got ported from my repository into the kernel although
most devices don't work at all with the current inkernel driver (eg.
em2888, flash based, isdb-t, cx25843, some saa7114.. based devices).
here's some development status history starting in 2006.
http://mcentral.de/wiki/index.php5/Em2880/Status
moved over to a mailinglist and support people from 2007 - currently
http://mcentral.de/pipermail/em28xx/
there's almost nothing of that work merged yet, and there are tonns of
howtos out there which are based on all that right now.
regards,
Markus

one more thing which I forgot it also adds support for em2888 based
which also support

So it is more like a new driver. I tried merging them about half a
year ago (unsuccessfully, of course). In the end your driver worked
with that piece of hardware I have (it seem to produce an awful lot of
tracing though) and I stayed with it.

You could submit patches depricating it. Does the old driver support
something yours does not?

Mine (a Pinnacle-Apple-something, USB) does not work with it at all.

There are some devices with a knob available that reading that
register is currently
not implemented in the newer driver, netBSD people figured out that
interrupts are delivered
when a key gets pressed (even on the remote control). This is a
construction side at the moment
and it should be changed to something appropriate like the netBSD
people implemented.

There's one limitation I cut out the drx3975d (might re-add it within
the next week
to the git repository)
I know this one is required for the Pinnacle 330e and an Hauppauge based device.
If you have problems with your device please start a thread on the em28xx ML:
http://mcentral.de/pipermail/em28xx/

BTW, you forgot to a patch to include your driver into Kconfig of
drivers/media/video. Something like this, perhaps:

And the upper-level Makefile. Otherwise the driver wasn't even
compiled. It has some warnings regarding unused inc_ref/dec_ref, BTW
