clocksource: qcom: Move clocksource code out of mach-msm

2014-02-04T23:48:54+00:00

We intend to share the clocksource code for MSM platforms between legacy and multiplatform supported qcom SoCs. Acked-by: Olof Johansson Signed-off-by: Kumar Gala

ARM: msm: Switch to sched_clock_register()

2013-11-21T23:41:00+00:00

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. Signed-off-by: Stephen Boyd Acked-by: David Brown Signed-off-by: Kevin Hilman

clocksource: Put nodes passed to CLOCKSOURCE_OF_DECLARE callbacks centrally

2013-10-02T09:42:48+00:00

Instead of letting each driver call of_node_put do it centrally in the loop that also calls the CLOCKSOURCE_OF_DECLARE callbacks. This is less prone to error and also moves getting and putting the references into the same function. Consequently all respective of_node_put calls in drivers are removed.

Merge branch 'msm/cleanup' into next/cleanup

2013-08-13T22:12:20+00:00

From David Brown : * msm/cleanup: ARM: msm: Only compile io.c on platforms that use it iommu/msm: Move mach includes to iommu directory ARM: msm: Remove devices-iommu.c ARM: msm: Move mach/board.h contents to common.h ARM: msm: Migrate msm_timer to CLOCKSOURCE_OF_DECLARE ARM: msm: Remove TMR and TMR0 static mappings ARM: msm: Move debug-macro.S to include/debug ARM: msm: Don't compile __msm_ioremap_caller() unless used ARM: msm: Remove unused and unmapped MSM_TLMM_BASE for 8x60 Signed-off-by: Kevin Hilman

ARM: msm: Migrate msm_timer to CLOCKSOURCE_OF_DECLARE

2013-08-06T18:18:02+00:00

This allows us to remove the init_time callback in the DT machine descriptors, shrinking the code. Signed-off-by: Stephen Boyd Signed-off-by: David Brown

Merge tag 'remove-local-timers' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm into next/cleanup

2013-07-23T23:54:15+00:00

From Stephen Boyd: Now that we have a generic arch hook for broadcast we can remove the local timer API entirely. Doing so will reduce code in ARM core, reduce the architecture dependencies of our timer drivers, and simplify the code because we no longer go through an architecture layer that is essentially a hotplug notifier. * tag 'remove-local-timers' of git://git.kernel.org/pub/scm/linux/kernel/git/davidb/linux-msm: ARM: smp: Remove local timer API clocksource: time-armada-370-xp: Divorce from local timer API clocksource: time-armada-370-xp: Fix sparse warning ARM: msm: Divorce msm_timer from local timer API ARM: PRIMA2: Divorce timer-marco from local timer API ARM: EXYNOS4: Divorce mct from local timer API ARM: OMAP2+: Divorce from local timer API ARM: smp_twd: Divorce smp_twd from local timer API ARM: smp: Remove duplicate dummy timer implementation Resolved a large number of conflicts due to __cpuinit cleanups, etc. Signed-off-by: Olof Johansson

arm: delete cpuinit/CPUINIT usage from all ARM users

2013-07-14T23:36:52+00:00

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) and are flagged as __cpuinit -- so if we remove the __cpuinit from the arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit related content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the ARM uses of the __cpuinit macros from C code, and all __CPUINIT from assembly code. It also had two ".previous" section statements that were paired off against __CPUINIT (aka .section ".cpuinit.text") that also get removed here.

ARM: msm: Divorce msm_timer from local timer API

2013-06-25T00:46:50+00:00

Separate the msm_timer from the local timer API. This will allow us to remove ARM local timer support in the near future and gets us closer to moving this driver to drivers/clocksource. Acked-by: David Brown Acked-by: Marc Zyngier Cc: Daniel Walker Cc: Bryan Huntsman Signed-off-by: Stephen Boyd

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.
