How time flies...

The original series that this was part of was never fully merged. This was (in
part) due to some general regmap changes being required [1]. In the meantime
someone else has submitted (nearly the same) changes that were merged into
regmap [2], so I could try resubmitting my patches. These have now been included
downstream in OpenWrt for a few months too, where they are using the regmap MDIO
support, but I understand that out-of-tree consumers aren't usually up for
consideration.

Best,
Sander
