• 18952f20f   clocksource: bcm2835: Switch to sched_clock_register() ... Browse Code »

  The 32 bit sched_clock interface now supports 64 bits. Upgrade to
  the 64 bit function to allow us to remove the 32 bit registration
  interface.

• 38ff87f77   sched_clock: Make ARM's sched_clock generic for all architectures ... Browse Code »

  Nothing about the sched_clock implementation in the ARM port is
  specific to the architecture. Generalize the code so that other
  architectures can use it by selecting GENERIC_SCHED_CLOCK.

• effbfdd7b   clocksource: pass DT node pointer to init functions ... Browse Code »

  In cases where we have multiple nodes of the same type, we may need the
  node pointer to know which node was matched. Passing the node pointer
  also keeps the init function from having to match the node a 2nd time.

  Update bcm2835, vt8500, and tegra20 init functions for the new function
  prototype. Further tegra20 clean-ups are in follow-up commit.

• c1b724f66   ARM: bcm2835: make use of CLKSRC_OF ... Browse Code »

  Using CLKSRC_OF enables deletion of the SoC-specific header
  bcm2835_timer.h, replacing the custom function bcm2835_timer_init() with
  the standardized automatic clocksource_of_init().

• 6bb27d734   ARM: delete struct sys_timer ... Browse Code »

  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.

• ee4af5696   ARM: bcm2835: add system timer ... Browse Code »

  The System Timer peripheral provides four 32-bit timer channels and a
  single 64-bit free running counter. Each channel has an output compare
  register, which is compared against the 32 least significant bits of the
  free running counter values, and generates an interrupt.

  Timer 3 is used as the Linux timer.

  The BCM2835 also contains an SP804-based timer module. However, it
  apparently has significant differences from the standard SP804 IP block,
  and Broadcom's documentation recommends using the system timer instead.

  This patch was extracted from git://github.com/lp0/linux.git branch
  rpi-split as of 2012/09/08, and modified as follows:

  * s/bcm2708/bcm2835/.
  * Modified device tree vendor prefix.
  * Moved to drivers/clocksource/. This looks like the desired location for
  such code now.
  * Added DT binding docs.
  * Moved struct sys_timer bcm2835_timer into time.c to encapsulate it more.
  * Simplified bcm2835_time_init() to find one matching node and operate on
  it, rather than looping over all matching nodes. This seems more
  consistent with other clocksource code.
  * Simplified bcm2835_time_init() using of_iomap().
  * Renamed struct bcm2835_timer.index to match_mask to better represent its
  purpose.
  * s/printk(PR_INFO/pr_info(/
