I have tested this series with x86/Qemu running the sample. And the same
on real custom ARM64 hardware. Additionally, I ported a custom driver on
ARM64 to use this (well, it just uses the trivial
property_read().required_by()). So if it helps

Tested-by: Dirk Behme <dirk.behme@de.bosch.com>

for the whole series.

Btw, many thanks for working on this!
