For now it seems that we are not using any Renesas specific
implementation detail. The driver actually matches the Cadence
compatible. But since we have no other user, and since we know this IP
is generic, we preferred to add a Renesas compatible to match the actual
implementation of the Cadence IP, in case we later figure out
differences with the original HDL. I thought this was the correct policy
to apply.

Thanks,
Miquèl
