The Atlas Scientific pH OEM sensor is a small circuit to be embedded in
end products to measure the pH value with any commercially available pH
electrode
The currently supported SAM0 MCUs (samd21, saml21, saml1x) share the
same RTC peripheral, yet each of them carries it's own copy of the RTT
driver.
Unify the drivers and move them to sam0_common.
- Indicated that the hardware reset signal is used to reset the device and that
OpenOCD will that connect under reset
- Added troubleshooting for flashing using hardware reset
- Removed previous troubleshooting for flashing, as this issue is no longer
present since OpenOCD connects under reset
This removes doing `filter-out periph_hwrng, $(FEATURES_PROVIDED)`
after processing `cpu/$(CPU)/Makefile.features`.
The current solution is a HACK as `CPU_MODEL` is currently not available
at that moment but will be in the near future.
It will allow always including `cpu/$(CPU)/Makefile.features` after
`boards/$(BOARD)/Makefile.features`.
It is a part of moving `CPU/CPU_MODEL` definitions to `Makefile.features`.
Previously, there was a very tight allowed margin (100us), then some
special cases for platforms for which the test would otherwise fail,
increasing the margin.
This turned out to be a maintanance burden, as each slightly special
board needed a PR adding the special case.
This commit sets a quite large margin (1000us, 0.1% of total delay),
which should be large enough to not trip over platform-induced timer
inaccuracies, but still verify that the module is using timers
correctly.
(This is not a timer accuracy test.)
Check that some variables are not exported in the build system.
This should track variables that managed to not be exported anymore so
that they do not reappear in a BSP.
It is not a whitelist but just a way to keep things cleaned in the
future.
UART devices are now configured using static array in header files instead of static variables in implementation to be able to define UART_NUMOF using the size of the array instead of a variable.

This will allow sharing it between Makefile.include and
makefiles/info-global.inc.mk.
Also some common variables definition can also be moved to here.
Part of moving CPU/CPU_MODEL definition to Makefile.features to have it
available before Makefile.include.
