      ARM: sa1100: convert timer suspend/resume to clock_event_device · e3cbfb62
      由 Stephen Warren 提交于 
      Move sa1100's timer suspend/resume functions from struct sys_timer
sa1100_timer into struct clock_event_device ckevt_sa1100_osmr0. This
will allow the sys_timer suspend/resume fields to be removed, and
eventually lead to a complete removal of struct sys_timer.

      ARM: set arch_gettimeoffset directly · 23c197b7
      由 Stephen Warren 提交于 
      remove ARM's struct sys_timer .offset function pointer, and instead
directly set the arch_gettimeoffset function pointer when the timer
driver is initialized. This requires multiplying all function results
by 1000, since the removed arm_gettimeoffset() did this. Also,
s/unsigned long/u32/ just to make the function prototypes exactly
match that of arch_gettimeoffset.

      time: convert arch_gettimeoffset to a pointer · 7b1f6207
      由 Stephen Warren 提交于 
      Currently, whenever CONFIG_ARCH_USES_GETTIMEOFFSET is enabled, each
arch core provides a single implementation of arch_gettimeoffset(). In
many cases, different sub-architectures, different machines, or
different timer providers exist, and so the arch ends up implementing
arch_gettimeoffset() as a call-through-pointer anyway. Examples are
ARM, Cris, M68K, and it's arguable that the remaining architectures,
M32R and Blackfin, should be doing this anyway.

Modify arch_gettimeoffset so that it itself is a function pointer, which
the arch initializes. This will allow later changes to move the
initialization of this function into individual machine support or timer
drivers. This is particularly useful for code in drivers/clocksource
which should rely on an arch-independant mechanism to register their
implementation of arch_gettimeoffset().

This patch also converts the Cris architecture to set arch_gettimeoffset
directly to the final implementation in time_init(), because Cris already
had separate time_init() functions per sub-architecture. M68K and ARM
are converted to set arch_gettimeoffset to the final implementation in
later patches, because they already have function pointers in place for
this purpose.

      cris: move usec/nsec conversion to do_slow_gettimeoffset · 547046f2
      由 Stephen Warren 提交于 
      Move usec to nsec conversion from arch_gettimeoffset() to
do_slow_gettimeoffset(); in a future patch, do_slow_gettimeoffset()
will be used directly as the implementation of arch_gettimeoffset(),
so needs to perform all required calculations.
