* ARM: call of_clk_init from default time_init handlerSebastian Hesselbarth2013-09-291-12/+17
| | | | | | | | | | | | | Most DT ARM machs require common clock providers initialized before timers. Currently, arch/arm machs use .init_time to call of_clk_init right before clocksource_of_init. This prevents to remove that callback and use the default one instead. This patch adds a call to of_clk_init() to the default .init_time callback for COMMON_CLK enabled machs to allow to remove custom callbacks where applicable. While at it, also reorder includes alphabetically. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>
* sched_clock: Make ARM's sched_clock generic for all architecturesStephen Boyd2013-06-121-3/+1
| | | | | | | | | | 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: make machine_desc->init_time default to clocksource_of_initArnd Bergmann2013-04-111-1/+6
| | | | | | | | | | | | Originally from a default machine descriptor patch from Arnd, pull out just the default call to clocksource_of_init part. This is needed so that platforms can simply remove .init_time calls as they are converted to use clocksource_of_init.

* ARM: delete struct sys_timerStephen Warren2012-12-241-8/+1
| | | | | | | | | | | | | | | | | | 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.

* ARM: remove struct sys_timer suspend and resume fieldsStephen Warren2012-12-241-34/+0
| | | | | | | | | | | These fields duplicate e.g. struct clock_event_device's suspend and resume fields, so remove them now that nothing is using them. The aim is to remove all fields from struct sys_timer except .init, then replace the ARM machine descriptor's .timer field with a .init_time function instead, and delete struct sys_timer.

* ARM: set arch_gettimeoffset directlyStephen Warren2012-12-241-14/+0
| | | | | | | | | | | | | | | | | | | remove ARM's struct sys_timer .offset function pointer, and instead directly set the arch_gettimeoffset function pointer when the timer driver is initialized. This requires multiplying all function results by 1000, since the removed arm_gettimeoffset() did this. Also, s/unsigned long/u32/ just to make the function prototypes exactly match that of arch_gettimeoffset.

* time: convert arch_gettimeoffset to a pointerStephen Warren2012-12-241-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, whenever CONFIG_ARCH_USES_GETTIMEOFFSET is enabled, each arch core provides a single implementation of arch_gettimeoffset(). In many cases, different sub-architectures, different machines, or different timer providers exist, and so the arch ends up implementing arch_gettimeoffset() as a call-through-pointer anyway. Examples are ARM, Cris, M68K, and it's arguable that the remaining architectures, M32R and Blackfin, should be doing this anyway. Modify arch_gettimeoffset so that it itself is a function pointer, which the arch initializes. This will allow later changes to move the initialization of this function into individual machine support or timer drivers. This is particularly useful for code in drivers/clocksource which should rely on an arch-independant mechanism to register their implementation of arch_gettimeoffset(). This patch also converts the Cris architecture to set arch_gettimeoffset directly to the final implementation in time_init(), because Cris already had separate time_init() functions per sub-architecture. M68K and ARM are converted to set arch_gettimeoffset to the final implementation in later patches, because they already have function pointers in place for this purpose.

| | | | | | | | | | | | | | | | | At the moment, read_persistent_clock is implemented at the platform level, which makes it impossible to compile these platforms in a single kernel.

* ARM: sched_clock: allow init_sched_clock() to be called earlyRussell King2011-01-111-0/+4
| | | | | | | | | | | | | | sched_clock is supposed to be initialized early - in the recently added init_early platform hook. However, in doing so we end up calling mod_timer() before the timer lists are initialized, resulting in an oops. Split the initialization in two - the part which the platform calls early which starts things off. The addition of the timer can be delayed until after we have more of the kernel initialized - when the normal time sources are initialized. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change.

Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies.

* [ARM] 3855/1: Add generic time supportKevin Hilman2006-09-281-0/+6
| | | | | | | | | | | | | | | | This patch adds Generic time-of-day support for the ARM architecture. The support is currently added using #ifdef's so that it can support sub-arches that do not (yet) have a clocksource added. As sub-arches add clocksource support, they should 'select GENERIC_TIME' Signed-off-by: Deepak Saxena <dsaxena@mvista.com> Signed-off-by: Daniel Walker <dwalker@mvista.com> Signed-off-by: Kevin Hilman <khilman@mvista.com> Acked-by: John Stultz <johnstul@us.ibm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [PATCH] fix next_timer_interrupt() for hrtimerTony Lindgren2006-03-061-4/+6
| | | | | | | | | | | | | | | | | | | | | Also from Thomas Gleixner <tglx@linutronix.de> Function next_timer_interrupt() got broken with a recent patch 6ba1b91213e81aa92b5cf7539f7d2a94ff54947c as sys_nanosleep() was moved to hrtimer. This broke things as next_timer_interrupt() did not check hrtimer tree for next event. Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ, VST) implementations, as the system can be in idle when next hrtimer event was supposed to happen. At least ARM and S390 currently use next_timer_interrupt().

* [ARM] Cleanup ARM includesRussell King2006-01-031-3/+0
| | | | | | | | | | | | | | | | arch/arm/kernel/entry-armv.S has contained a comment suggesting that asm/hardware.h and asm/arch/irqs.h should be moved into the asm/arch/entry-macro.S include. So move the includes to these two files as required. Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h includes which use those facilities, and remove asm/io.h from kernel/process.c. Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm and arch/arm/mach-footbridge. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
