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=20
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 t=
he patch
and try to work on your recommendation.

Thanks
