looked closer to cards without eeprom.

This Items ITV-301 seems to be identical with current Manli MTV301.

http://www.manli.com/eng_products_detail.php?pCatId=63&productId=105#
http://pcgeneral.hu/images/itv301.jpg

Andre in his later patches uses also the IR configuration of prior Manli
cards we have.

The above card(s) use now saa7135 chips, the older ones we have saa7130.

Because of that, there is a flaw in Andre's patch.
He uses, like on saa7130 mono only chips, LINE2 input from tuner to the
saa7135. This is only mono sound from the tuner.

Instead amux = TV should be used to get stereo sound on that board.
(Some older cards still have mono from tuner additionally in their
configuration)

This, in combination with the Manli IR, the different audio clock
compared to the Manli cards and the MK3 tuner would justify a new entry
for the card I think.

Could you try, if .amux = TV works for Television?

Reworked patches must go to linux-media@xxxxxxxxxxxxxxx

This is the valid list now and "patchwork", patchwork.kernel.org for
linux-media, tries to collect the patches from that list.

Make sure to run "make checkpatch" before and send also as .patch
attachment. Andre's mailer breaks the lines.

I'm not sure for what that gpiomask is needed, but else you could try
for now with

"options saa7134 card=27 tuner=38 audio_clock_override=0x00187de7"

That will also have only mono sound for Television.

Cheers,
Hermann
