Yes, as a matter of fact I screened the kernel concerning this multi
gpio stuff but could not quite find many examples and no mentioning
anywhere whether or not this is actually allowed. So I kind of assumed
that this may just not really be allowed and cooked up my patch which
is anyway kind of a cleaner solution. I mean explicitly modelling the
GPIO into some intermediate regulator supplying the others.

Yes, da-da and HDMI works again. Thanks!
I will still try to get my other patch in as like mentioned above I
feel it is a cleaner solution to our regulator setup.
BTW: Have you heard of lore as well? I believe it is the better mailing
list archive as of today:
