Have you ignored Krzysztof's comments on this? I don't see a response or
a reaction to his comments about the compatibles on the last version.
Additionally, where is the user for these? I don't see any drivers that
actually make use of these.

Why do you need to have 2 compatibles (and therefore 2 devices) for the
clint? I thought the clint was a single device, of which the mtimer and
mswi bits were just "features"? Having split register ranges isn't a
reason to have two compatibles, so I must be missing something here...

Thanks,
Conor.
