Would you mind posting a lore link? I'll gladly chime in.

Drivers are OF-only until they aren't. Vide: lots of discussions
currently about supporting ARM laptops and servers with mixed DT-ACPI
setup.

The overhead of going through the fwnode pointer is absolutely
negligible while using generic accessors allows taking secondary
fwnodes into account.

Please don't tell me people are going around the kernel converting
drivers to using of_ routines?
