This patch series changes the 32-bit time type (timespec/itimerspec) to the
64-bit one
(timespec64/itimerspec64), since 32-bit time types will break in the year 2038.
This patch series introduces new methods with timespec64/itimerspec64 type,
and removes the old ones with timespec/itimerspec type
This patch converts the timepsec type to timespec64 type, and converts the
itimerspec type to itimerspec64 type for the k_clock callback functions.
This patch also converts the timespec type to timespec64 type for
timekeeping_clocktai()
function which is used only in the posix-timers.c file.

This patch converts the posix clock operations over to the new methods with

This patch introduces the 'struct itimerspec64' for 64bit to replace itimerspec,

itimerspec_to_itimerspec64(), that makes itimerspec to ready for 2038 year.

Some drivers require copying unaligned ethernet addresses.
Using memcpy() causes checkpatch warnings and may cause
regressions (someone will "fix" alignment of packed structure)

That just means we could in future consider to consistently add support
