reboot: arm: change reboot_mode to use enum reboot_mode

2013-07-09T17:33:29+00:00

Preparing to move the parsing of reboot= to generic kernel code forces
the change in reboot_mode handling to use the enum.

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2013-07-06T21:09:38+00:00

Pull timer core updates from Thomas Gleixner:
 "The timer changes contain:

   - posix timer code consolidation and fixes for odd corner cases

   - sched_clock implementation moved from ARM to core code to avoid
     duplication by other architectures

   - alarm timer updates

   - clocksource and clockevents unregistration facilities

   - clocksource/events support for new hardware

   - precise nanoseconds RTC readout (Xen feature)

   - generic support for Xen suspend/resume oddities

   - the usual lot of fixes and cleanups all over the place

  The parts which touch other areas (ARM/XEN) have been coordinated with
  the relevant maintainers.  Though this results in an handful of
  trivial to solve merge conflicts, which we preferred over nasty cross
  tree merge dependencies.

  The patches which have been committed in the last few days are bug
  fixes plus the posix timer lot.  The latter was in akpms queue and
  next for quite some time; they just got forgotten and Frederic
  collected them last minute."

drivers/dma: remove unused support for MEMSET operations

2013-07-03T23:07:42+00:00

There have never been any real users of MEMSET operations since they
have been introduced in January 2007 by commit 7405f74badf4 ("dmaengine:
refactor dmaengine around dma_async_tx_descriptor").  Therefore remove
support for them for now, it can be always brought back when needed.

sched_clock: Make ARM's sched_clock generic for all architectures

2013-06-12T21:02:13+00:00

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.

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.

Merge tag 'arm-perf-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux into next/cleanup

2012-09-05T05:12:41+00:00

From Will Deacon:

Bunch of perf updates for the ARM backend that pave the way for
big.LITTLE support in the future. The separation of CPU and PMU code
is also the start of being able to move some of this stuff under
drivers/.

* tag 'arm-perf-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux:
  ARM: perf: move irq registration into pmu implementation
  ARM: perf: move CPU-specific PMU handling code into separate file
  ARM: perf: prepare for moving CPU PMU code into separate file
  ARM: perf: probe devicetree in preference to current CPU
  ARM: perf: remove mysterious compiler barrier
  ARM: pmu: remove arm_pmu_type enumeration
  ARM: pmu: remove unused reservation mechanism
  ARM: perf: add devicetree bindings for 11MPcore, A5, A7 and A15 PMUs
  ARM: PMU: Add runtime PM Support

ARM: pmu: remove arm_pmu_type enumeration

2012-08-23T10:35:51+00:00

The arm_pmu_type enumeration was initially introduced to identify
different PMU types in the system, the usual one being that on the CPU
(ARM_PMU_DEVICE_CPU). With the removal of the PMU reservation code and
the introduction of devicetree bindings for the CPU PMU, the enumeration
is no longer required.

This patch removes the enumeration and updates the various CPU PMU
platform devices so that they no longer pass an .id field referring
to identify the PMU type.

ARM: iop3xx: use fixed PCI i/o mapping

2012-07-26T14:10:04+00:00

Move iop33x and iop32x PCI to fixed i/o mapping and remove io.h. This
changes the PCI bus addresses from the cpu address to 0 based. It appears
that there is translation h/w for this, but its untested.

Not sure what to do with io_offset. I think it should always be 0.
AFAICT, PCI setup is skipped if the ATU is already setup.

ARM: PCI: provide a default bus scan implementation

2012-05-13T16:12:17+00:00

Most PCI implementations perform simple root bus scanning.  Rather than
having each group of platforms provide a duplicated bus scan function,
provide the PCI configuration ops structure via the hw_pci structure,
and call the root bus scanning function from core ARM PCI code.
