maintainers:

description:
The MTU2 is a multi-purpose, multi-channel timer/counter with configurable clock inputs
and programmable compare match.
Channels share hardware resources but their counter and compare match value are
independent. The MTU2 hardware supports five channels indexed from 0 to 4.
