[linux-dvb] new fidbirq and hsync interrupt edge
HI
Better results are obtained in new fidbirq when triggering only
on falling 0x*0680 (or rising) edge of the hsync (tested on tt13+budget
patch).
Triggering on both edges (0x*06c0) tends to loose some packets
and are visible as sporadic artefacts when viewing with ts2ps|mplayer.
As my stv0299 still isn't working, I tested that only for patched
card.
Therefore, in case of patched cards, I used falling edge triggering,
and in all other cases (normal budget cards), I left triggering on
both edges, as it was in the original vesion.
Also, I added minimum debi commands for diseqc to work on
patched cards.
Think these chages can be submitted to CVS
