That way I see really low (or not at all) relation between out
(not)Broadcom bus and present AMBA bus.


Ehh, sounds like one more renaming to functions, defines, prefixes.

Let's wait for Arend comments, he was the one voting for not-bcm-specific name.

Hi RafaÅ,

Still think its better to stick with a generic name even if currently you only come across this in Broadcom chips right now. I do agree that the term 'axi' is implying something else than what this bus driver is providing. The name 'axi-dmp' I gave earlier may be more to the point.

I also looked at the amba driver after receiving comments on the brcmaxi library module (this is what Hauke Mehrtens referred to) and came to similar conclusion as you did. It does however support PM properly so you may want to get inspiration in that area. I also noticed a reference to AMBA term APB which is a different bus in the AMBA family. AXI was introduced later as higher performance bus (in AMBA rev3 if I remember correctly).
