MSEC and SEC are now usable on TIMER(0) without having USEC
pm is configured by used hardware
OLD configuration values are translated for backward compatibility
prefer rtt for ZTIMER_SEC
avoid doing partial ztimer setup if auto_init_ztimer is disabled
before this patch some const pointers might have been definend to values
that a user who disables auto_init for ztimer does not like.
- add some xtimer specific defines some tests rely on
- provide the following missing functions:
- xtimer_ticks()
- xtimer_set_timeout_flag()
- xtimer_set_timeout_flag64()
- xtimer_spin()
Add a function that sleeps for ms instead of µs.
This will make the conversion to ztimer easier for users as now there is
a direct mapping to ZTIMER_MSEC.
