Should not the defines start with J7200_WIZ? SERDES0 seems like a too
generic prefix, at least to me.

Thanks, good point. I am not sure if WIZ should even be used.. It is
a TI internal prefix for various serdes solutions, but I agree that
SERDES0 is too generic a terminology. That said, we should cleanup
include/dt-bindings/mux/mux-j721e-wiz.h as well, prior to introducing
j7200 changes.

Right. As maintainer for the directory in question, I should have
been on Cc for that series too, but it appears I wasn't. Hence, I

yes, you should have been. The following commit introduced it.

commit b766e3b0d5f6 ("arm64: dts: ti: k3-j721e-main: Add system controller
node and SERDES lane mux")

didn't notice that file until now when I went looking for it. Why
wasn't I on Cc?

Got through the SoC tree - an oversight on our part[1] and should'nt have,
Apologies on the bad call.

I would like to propose the following:
a) The header should be renamed to be something more human friendly.
b) The header should be renamed to be something TI specific and NOT per
TI SoC.
c) The macros need renaming to be less generic as it stands right now.


If you ack the changes, I am guessing that the changes will impact dts
a lot and would rather take the cleanups through SoC tree to maintain
bisectability? OR I can pick on an immutable tag from you with just the
header file change and pick on the dts - but I doubt that would be
bisectable. Just worried that I have picked a bunch of cleanups already
on the dts for 5.10, and would like to avoid a merge conflict.

[Our mails crossed.]

I do not have a tree and dt-patches should normally not go *through* me.
But I'd still like to see what's happening.

I did not realize this was going to cause a *lot* of churn in the dt
files. How bad can it be when the file is new in this cycle? And is it
worth it? But it seems you all see problems with the current naming and
in that case it must surely be better to fix it early?

And if it's a lot, maybe it needs to be more than one patch? I get the
feeling this will need to be taken care of by someone other than me,
because I'm just the maintainer of a very small subsystem and I don't
normally have to deal with "big" issues involving several trees. I would
be a bottleneck.

Cheers,
Peter
