So on omap4/5 there are timers with a single IO register and with
dual mapped IO registers.

Yes I tried, but see the above. The compatible property is the same for
single mapped and dual mapped timers on the same SoC for omap4/5.

It's the same situation for clocks, the same compatible is used for
timers with one clock and timers with two clocks for example on dra7.

I'll check the description again to clarify this, maybe it's not
clear yet.

Oops sorry looks like I forgot to update the version.
