ARM: msm: Stop counting before reprogramming clockevent

2013-03-22T17:45:39+00:00

If the clockevent is forcibly reprogrammed to have a different
match value we mistakenly assume the timer is not ticking and
program a new match value while the timer is running. Although we
clear the timer before programming a new match, it's better to
stop the timer before clearing it so that we're sure the proper
amount of ticks are counted. Failure to do so can lead to missed
ticks and system hangs.

Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

2013-02-21T22:58:40+00:00

Pull ARM SoC cleanups from Arnd Bergmann:
 "A large number of cleanups, all over the platforms.  This is dominated
  largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
  others moving code out of arch/arm into more appropriate subsystems.

  The clocksource and irqchip drivers are now abstracted to the point
  where platforms that are already cleaned up do not need to even
  specify the driver they use, it can all get configured from the device
  tree as we do for normal device drivers.  The clocksource changes
  basically touch every single platform in the process.

  We further clean up the use of platform specific header files here,
  with the goal of turning more of the platforms over to being
  "multiplatform" enabled, which implies that they cannot expose their
  headers to architecture independent code any more.

  It is expected that no functional changes are part of the cleanup.
  The overall reduction in total code lines is mostly the result of
  removing broken and obsolete code."

ARM: msm: proc_comm_boot_wait should not be __init

2013-02-12T01:42:28+00:00

msm_smd_probe is a driver probe function and may get
called after the __init time, so it must not call
any __init function, as the link-time warning reports.
Take away the __init annotation on proc_comm_boot_wait
to fix this.

Without this patch, building msm_defconfig results in:

WARNING: vmlinux.o(.text+0xb048): Section mismatch in reference from the function msm_smd_probe() to the function .init.text:proc_comm_boot_wait()
The function msm_smd_probe() references
the function __init proc_comm_boot_wait().
This is often because msm_smd_probe lacks a __init
annotation or the annotation of proc_comm_boot_wait is wrong.

From Shawn Guo:
The series cleans up ARCH_HAS_DECOMP_WDOG and arch_decomp_wdog which
are unused on ARM architecure.  Samsung has some code setting up wdog
in arch_decomp_wdog().  But since CONFIG_S3C_BOOT_WATCHDOG is defined
nowhere, it will not run.  Otherwise, system can not boot at all when
wdog is set up but no one pats it.

This creates irqchip initialization infrastructure from Thomas

ARM: use clockevents_config_and_register() where possible

2013-01-14T18:12:42+00:00

The clockevent core is able to figure out the best mult and shift,
calculate min_delta_ns and max_delta_ns, with the necessary info passed
into clockevents_config_and_register().  Use this combined configure
and register function where possible to make the codes less error prone
and gain some positive diff stat.
