This series is part of some clean-ups to reduce the open coded parsing
of "reg" and "ranges" in the kernel. As those are standard properties,
the common DT code should be able to handle parsing them. However, there
are a few gaps in the API for what some drivers need which this series
addresses (pun intended).
I intend to add these helpers for v6.4 and then convert the users in
v6.5 to avoid any dependency issues. This series and the WIP conversions
are on this branch[1].
