df5c319978 from
https://github.com/RIOT-OS/RIOT/pull/19558 broke the clock
configuration of the Z1 by relying on the incorrect documentation of
what clock is actually used. Closely reading the convoluted clock
initialization code revealed that no XT2 crystal is present (as also
indicated by some comments in `board.c`), contradicting the
`#define MSP430_HAS_EXTERNAL_CRYSTAL 1` in the `board.h`.
This now should restore behavior (but with calibrated DCO than
hard coded magic numbers).
Provide a common clock initialization driver rather than leaving
clock initialization to the boards code. A declarative description of
the board's clock configuration using a struct does still allow to
fine-tune settings. In addition, a board is still allowed to just
provide a custom `void clock_init(void)` if there really is the need
to do crazy things.
- most were trivial
- missing group close or open
- extra space
- no doxygen comment
- name commad might open an implicit group
this hould also be implicit cosed but does not happen somtimes
- crazy: internal declared groups have to be closed internal
* also added a trailing underscore to header guards for consistency
Commit for PR 2623, repairing header file include guards.
This PR is intended to fix the include guards in files under RIOT/boards
SQUASH ME: fix underscore removal overdos
SQUASH ME: consistent macro naming
SQUASH ME: missed that one
SQUASH ME: fixed overdo
SQUASH ME: consistency
