the feature to be enabled/disabled via the ACSPCIE block are the same as
well i.e. "register layout can be inferred". The same goes for the
compatibles listed below in my previous reply i.e. they aren't bugs.
Same IP and integration across SoCs and hence reused in the sense of
Hardware and not Software. I hope this clarifies the rationale for the
"reuse".

You mix re-use with fallback. These are almost never the same blocks,
which you imply here.
I know that the IP is the same, the bits are the same and those bits enable
the same functionality of the IP across the SoCs. If you still insist that
they are not same, I don't know what to say anymore.

You can say what we have been saying on mailing lists all the time:
hardware datasheets lie and sometimes you find one, tiny tiny
difference. If you are uncertain, please consult your SoC maintainer on
this matter.

Best regards,
Krzysztof
