I tried to use the updated patchset with my at24 & beaglebone capemanager patches.

I have a big problem with the removal of the raw of_* access APIs.

Take for instance the case where you have multiple slot accessing different EEPROMs.

In that case there is no per-device node mapping; it’s a per-sub node.

For now I’m exporting the of_* accessors again, please consider exposing the of_* API again.
