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")

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.

your thoughts?
