|  | This assumes an existence of mboard_regs_control in PeriphManagerBase
and implements most TK controls there. All the *_periphs.py files can
now use a common class for registers, including the TK access, but also
git hash, build date, and device ID access.
This also fixes two issues:
- set_timekeeper_time() and set_tick_period() had a bug that would
  incorrectly calculate the upper 32 bits of their respective registers.
- N3xx had a bug that would swap around set time now and next PPS. This
  got auto-fixed because the common code never had this bug. |
