I hope this subject wasn't previously discussed, as I couldn't find a trace ...

The basic question is : why can't the PXA27x reset the AC97 bus in front of an
wm9713 ?

And more precisely, I'd like to know :
 - are there any references to this bug (Intel note, mailing list ref, ...)
 - is it a hardware bug on PXA27x side ?
 - is it a hardware bug on wm9713 side ?
 - is there a known generic workaround (assuming GPIO113 is connected to wm9713
reset line is not generic for me) ?
 - is there a known platform where this bug does not happen ?
