We may need to set SITRE before programming slave_data.quoted

Do you have a documentation cite for this or is it random fiddling with a driver you can't test ?quoted

It is good to enable SITRE register before programming it and all Intel controllersquoted
That sounds like someone quoting religion. Documentation cite please.SLC90E66 datasheet only says that SIDETIM register has no effect without SITRE bit set.
Alan, is this explanation sufficient to ACK this patch? (Thanks Sergei for digging it out.) Jeff, would it be possible to queue patches #01-15 for 2.6.39 if there are no further concerns with them (thus leaving the merging of PIIX-like drivers for later)? They got additional testing on ICH4 and they look mostly safe & straight-forward compared to #16-21. Thanks, Bartlomiej
