In this patchset, I tried to reuse Marcin's patch which was posted on 2017/12/18.
https://lkml.org/lkml/2017/12/18/211
With my patch([v1,2/7] mdio_bus: modify fwnode phy related functions), I've made
modifications to this(v1,1/7) patch to adapt to the changes in the kernel.

Yes attempt is to consolidate DT and ACPI into fwnode. Sure, I'll revisit the patch
and try to work on your recommendation.
