2009-12-13ARM: fix sa1100 buildRussell King
Fix: arch/arm/mach-sa1100/generic.c:117: error: redefinition of 'cpufreq_get' include/linux/cpufreq.h:299: error: previous definition of 'cpufreq_get' was here cpufreq_get() is used on these platforms to tell drivers what the CPU frequency is, and therefore the bus frequency - which is critical for setting the PCMCIA and LCD timings. Adding ifdefs to these drivers to select cpufreq_get() or some other interface adds confusion. Making these drivers use some other interface for the normal paths and cpufreq stuff for the cpufreq notifier is insane as well. (Why x86 can't provide a version of cpufreq_get() which returns the CPU frequency when CPUFREQ is disabled is beyond me, rather than requiring a dummy zero-returning cpufreq_get(). Especially as they do: unsigned long khz = cpufreq_get(cpu); if (!khz) khz = tsc_khz; In other words, if CPUFREQ is disabled, get it from tsc_khz - why not provide a dummy cpufreq_get() which returns tsc_khz?)

2009-12-01ARM: SAMSUNG: Add plat-samsung as starting point for plat-s3c* movesBen Dooks
We inted to re-organise the plat-s3c/plat-s3c24xx/plat-s3c64xx into a more generic plat-samsung with less code in the other plat- directories to make it easier to port new devices and try and clear up some of the naming issues with newer devices. Start by creating a small arch/arm/plat-samsung with no actuall code in so we can move items in as we process them. Add this to arch/arm to allow it to build things once support is added.

2009-10-29iop: enable generic timeMikael Pettersson
This updates the IOP platform to use the kernel's generic time framework. With clockevent support in place, this reduces to selecting GENERIC_TIME and removing the platform's private timer ->offset() operation (iop_gettimeoffset). Tested on n2100, compile-tested for all plat-iop machines. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-10-29iop: clockevent supportMikael Pettersson
This updates the IOP platform to expose the interrupting timer 0 as a clockevent object. The timer interrupt handler is changed to call the clockevent ->event_handler() instead of timer_tick(), and ->set_next_event() and ->set_mode() operations are added to allow the mode of the timer to be updated (required for ONESHOT/NOHZ mode). Timer 0 must now be properly initialised, which requires a new write_tcr0() function from the mach-specific code. The mode of timer 0 must be read at the start of ->set_mode(), which requires a new read_tmr0() function from the mach- specific code. Initial setup of timer 0 is also rewritten to be more robust. Tested on n2100, compile-tested for all plat-iop machines. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2009-08-13Use kernel/Kconfig.preempt for ARMUwe Kleine-König
before this patch ARM had it's own definition of CONFIG_PREEMPT. Instead of that use the general definition provided in kernel/Kconfig.preempt. This patch changes the available options in *config. Namely PREEMPT isn't a stand alone bool anymore, but part of a 'choice' the following Kconfig symbols are added: PREEMPT_NONE PREEMPT_VOLUNTARY Selecting PREEMPT_NONE now produces exactly the code as not selecting PREEMPT before (apart from a comment in /sys/kernel/debug/tracing/(per_cpu/cpuX/)?trace). The only difference PREEMPT_VOLUNTARY does is that might_resched might reschedule. Both should't introduce regressions.

2009-06-16[ARM] S3C64XX: Initial support for DVFSMark Brown
This patch provides initial support for CPU frequency scaling on the Samsung S3C ARM processors. Currently only S3C6410 processors are supported, though addition of another data table with supported clock rates should be sufficient to enable support for further CPUs. Use the regulator framework to provide optional support for DVFS in the S3C cpufreq driver. When a software controllable regulator is configured the driver will use it to lower the supply voltage when running at a lower frequency, giving improved power savings. When regulator support is disabled or no regulator can be obtained for VDDARM the driver will fall back to scaling only the frequency.
