Hi all,

this is my third attempt to fix the ssd1307fb OLED driver reset. In the
second attempt [1] Rob suggested to take different aproach. That is to
apply what was originaly part of the first round and eventually merged
but reverted later on [2][3].

The last patch in this series is a fixup for the single user (in-tree)
that uses this OLED. Rob suggested the fixup may actually be applied
only after someone complains their display broke.

And a comment from Alexandre regarding the status of the Crystalfontz
platform:
