What you did is absolutely correct and renaming makes more
sense in 2/2.

Naahh.. OF by itself doesn't mean anything here on this driver. It
belongs to all the users that are using DT to enumerate it (Mostly
ARM). And they are going to use platform_driver interface. So,
code is well located currently too..

ACPI, I am not sure.. you need these routines in your pci stuff too?
Keep it this way:
- Keep all the common stuff across pci and platform in core.c
- everything else in pci and platform files.

I understood it when I tried to apply it at my end :)
