      clocksource: add common of_clksrc_init() function · ae278a93
      Stephen Warren authored
      It is desirable to move all clocksource drivers to drivers/clocksource,
      yet each requires its own initialization function. We'd rather not
      pollute <linux/> with a header for each function. Instead, create a
      single of_clksrc_init() function which will determine which clocksource
      driver to initialize based on device tree.
      
      Based on a similar patch for drivers/irqchip by Thomas Petazzoni.

      ARM: delete struct sys_timer · 6bb27d73
      Stephen Warren authored
      Now that the only field in struct sys_timer is .init, delete the struct,
      and replace the machine descriptor .timer field with the initialization
      function itself.
      
      This will enable moving timer drivers into drivers/clocksource without
      having to place a public prototype of each struct sys_timer object into
      include/linux; the intent is to create a single of_clocksource_init()
      function that determines which timer driver to initialize by scanning
      the device dtree, much like the proposed irqchip_init() at:
      http://www.spinics.net/lists/arm-kernel/msg203686.html
      
      Includes mach-omap2 fixes from Igor Grinberg.

      ARM: remove struct sys_timer suspend and resume fields · 7704c095
      Stephen Warren authored
      These fields duplicate e.g. struct clock_event_device's suspend and
      resume fields, so remove them now that nothing is using them. The aim
      is to remove all fields from struct sys_timer except .init, then replace
      the ARM machine descriptor's .timer field with a .init_time function
      instead, and delete struct sys_timer.

      ARM: samsung: register syscore_ops for timer resume directly · 656c669b
      Stephen Warren authored
      Instead of using struct sys_timer's resume function, register syscore_ops
      directly in s3c2410_timer_init(). This will allow the sys_timer suspend/
      resume fields to be removed, and eventually lead to a complete removal of
      struct sys_timer.

      time: convert arch_gettimeoffset to a pointer · 7b1f6207
      Stephen Warren authored
      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.
