[PATCH v4 00/18] i.MX8MM GPC improvements and BLK_CTRL driver

Hi all,

as it seems there is considerable interest in landing this despite some
spurious issues still being present, here's a 4th revision of the series
to not drop the ball. Even though I still did not have time to try to
dig into the open issues reported by Frieder, I think there is a high
chance that those are caused by something like a missed timing
constraint and not by something that would invalidate the overall design
of the GPC and BLK_CTRL interaction as laid out by this series. So I
still hope that we can land this series and apply fixes as we find them.

Regards,
Lucas
