Hi,
This patch enables LNB power on newer revision d1 Compro S350 and S300
DVB-S cards. While I don't have these cards to test with I'm confident
that this works. See
http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/7471 and http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/14296
and new windows driver as reference.

Hi Jan,
This does not fix the problem where the card is suppose to suspend and
the Voltage drops to 0V? Do you still require the windows registry
reference for this part?

Hi,
No, the aim of the patch is just to get the basic driver support for all
S300/S350 revisions. A windows regspy capture on a d1 revision card may
still be useful in double checking the GPIO values, but I already know
which GPIO controls LNB voltage:
GPIO15 = modulator reset
GPIO14 = LNB power
