Yep!

The idea is that new drivers for discrete (and sometimes even on-SoC)
components should be platform-agnostic (means no strict OF / ACPI
dependencies), so anybody can prototype devices on either of the
platforms.

As a matter of fact IIO subsystem is leading in this by cleaning up
most of the drivers towards that goal.

OF/ACPI explicit dependency makes sense when we 100+% sure that
IP in question won't ever appear on the other type of platform
(which I believe is very rare nowadays for most of the components).
