Yes. And the periph-id uses the base-addr (instead of the interrupt number), so I
have simpler code (i.e. dev_read_addr, which will just deref the node and get the
addr) instead of having to go to the tree again.

I’ll prepare the patch (need to check if additional work is needed for PWM) and
send this separately.
