OK, I get the problem here. So you need the ID to register an alias.
Still, the ID would be invalid when booted with DT and xti clock
registered using fixed rate clock bindings. So I'd suggest moving the
XTI clock ID definition from your DT binding header back to your driver,
leaving a comment in the header that this ID is reserved.
What do you think?
Best regards,
Tomasz
