I think you're right, we didn't make our intent clear here.

The patch enables ACPI _DSD to reuse existing DT "compatible" strings,
as described in Documentation/acpi/enumeration.txt, even without OF.
This kind of patch has some precedent, like for example:

    01427fe7c4b9 ("Input: adxl34x - make it enumerable in ACPI environment")

To clarify, for the UP2 board we don't actually need this patch as we
have an ACPI _HID - just thought it would might be an improvement for
others.

I'll improve the description and perhaps reorder this patch last for v2.
Or I can send separately if you prefer.

Thanks for your review!
