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 ?
