thanks for the update. Unfortunately this does not work:

The required power-supply for the power domains is still not yet available.
Does this series require some other patches as well?

Whats worse, starting with commit 9/9 [of: property: Simplify 
of_link_to_phandle()], other drivers fail to probe waiting for pinctrl to be 
available.

Apparently for some reason they are not probed again, once the pinctrl driver 
probed.
