Unfortunately, DT cannot do a binding with the ACPI names. Similarly, ACPI
cannot do a binding with the DT name.

The structure of binding name is also subject to different kind of rules
for DT and ACPI.

This driver supports both device tree and ACPI. That's why, two different
names are required.

Hmmm, wasn't the who get_property stuff supposed to make properties work on both ACPi & DT. I am not sure though about the current state of affairs on
that.


Get property works. It is able to abstract device driver properties. A driver doesn't need to know whether it is coming from acpi dsd or of.

However, no such mechanism exists for driver names due to nature of different naming requirements.

Of has its own match table and acpi has its own. Acpi also has ridiculous 8 character name limitation.
