[PATCH] selftests:timers: remove local CLOCKID defines
Posted by Shuah Khan 1 month, 2 weeks ago
timers tests defines CLOCKIDs locally. Remove all local CLOCKIDs except
CLOCK_HWSPECIFIC and use defines from time.h header file.

CLOCK_HWSPECIFIC and CLOCK_SGI_CYCLE are the same and CLOCK_SGI_CYCLE
is deprecated,
