any place to mark various compatible strings as deprecated?

any place to mark various compatible strings as deprecated?

[Kumar Gala]

Do we have anywhere to list out compatible strings that are deprecated  
and warn if the kernel sees one?

Wouldn't dtc be a better location for that? The kernel has to be backwards
compatible anyway, I don't really see a reason to warn there.

The reason is I want to eventually drop support in the kernel for some  
of the old compatibles.

It should certainly be in dtc.  Whether it should also be in the
kernel is debatable.  It's also really easy to add this to dtc.  Kumar
can you point me at the ones you're thinking of, and I'll add
appropriate checks to dtc (although probably not for a couple of weeks
when I return from vacation).

If it's something that shipped then I don't see how you can ever
do that. Best thing you can do is do fixups like prom_init does and
translate them to the preferred compatible string of the week.
