[PATCH v2 0/4] Fix ssd1307fb OLED driver reset

From: VokÃÄ Michal

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].

Next step is to apply a fixup for the single user (in-tree) that uses
this OLED. As Rob suggested, the fixup may be applied only after
someone complains their display broke.

I am not really sure what is the propper way to handle this so the
series contains the original patches + a minor fix in the docs and
the fixup as the last patch.

Adding Alexandre and Maxime from Bootlin to the Cc list as you seem
to be the last ones who touched the Crystalfontz platform. Your coment
regarding the status of the platform and whether the fixup should be
applied straight away or not at all will be appreciated.

Thank you,
