* CRIS: Remove legacy RTC driversJesper Nilsson2012-04-051-7/+0
| | | | | | | These old drivers are not used anymore, we use the ones in drivers/rtc. This allows us to remove some cruft in the CRIS timekeeping code. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
* clocksource: cris: Convert to clocksource_register_khzJohn Stultz2011-11-211-3/+1
| | | | | | | | | | | This converts the cris architecture to use clocksource_register_khz This is untested, so any help from maintainers would be appreciated.

* CRIS: GENERIC_TIME fixesJesper Nilsson2010-08-041-51/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | GENERIC_TIME was not functional for CRIS, giving random backward time jumps. For CRISv32 implement a new clocksource using the free running counter and ditch the arch_gettimeoffset. The random time jumps still existed, but turned out to be the write_seqlock which was missing around our do_timer() call. So switch over to GENERIC_TIME using the clocksource for CRISv32. CRISv10 doesn't have the free running counter needed for the clocksource trick, but we can still use GENERIC_TIME with arch_gettimeoffset. Unfortunately, there were problems in using the prescaler register to timer0 for the gettimeoffset calculation, so it is now ignored, making our resolution worse by the tune of 40usec (0.4%) worst case. At the same time, clean up some formatting and use NSEC_PER_SEC instead of 1000000000. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
* cris: Convert cris to use read/update_persistent_clockJohn Stultz2010-03-131-38/+2
| | | | | | | | | | | | | | | | | This patch converts the cris architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future. I have not built or tested this patch, so help from arch maintainers would be appreciated.

* CRIS v32: Update and improve kernel/time.cJesper Nilsson2008-02-081-98/+139
| | | | | | | | | - Shorten include paths to machine dependent header files. - Register name for first timer is now regi_timer0. - Remove raw_printk hack, use oops_in_progress instead. - Add handling of CPU frequency scaling for CRIS. - Remove regs parameter to timer_interrupt, get them from get_irq_regs instead. - Whitespace and formatting changes.

* [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto2006-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. 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. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.
