2008-04-14ARM: OMAP: Timer32K: Re-organize duplicated 32k-timer codeKevin Hilman
On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by setting the source to be the 32k clock instead of sys_clk. This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp code. Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based clocksource is not used. Instead the default 32k sync counter is used as the clocksource (see the clocksource in plat-omap/common.c.) This is important for sleep/suspend so there is a valid counter during sleep. Note that the suspend/sleep code needs fixing to check for overflows of this counter. In addition, the OMAP2/3 details are removed from timer32k.c leaving that with only OMAP1 specifics. A follow-up patch will move it from plat-omap common code to mach-omap1.

2008-01-28[ARM] Fix timer damage from d3d74453c34f8fd87674a8cf5b8a327c68f22e99Russell King
Move the xtime write mode seqlock into timer_tick(), so it only surrounds the call to do_timer(). This avoids a deadlock in update_process_times() ... hrtimer_get_softirq_time() which tries to get a read mode seqlock on xtime, thereby preventing booting.

2007-10-19Convert files to UTF-8 and some cleanupsJan Engelhardt
* Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>

2006-07-02[PATCH] ARM: fixup irqflags breakage after ARM genirq mergeThomas Gleixner

2006-06-26ARM: OMAP: Fix 32 kHz timer and modify GP timer to use GPT1Timo Teras
The dmtimer framework update broke 32 kHz timer as udelay() does not work before system timer is started (and GPT1 should not be reset). This also makes the GP timer use GPT1. This requires a fix in clock framework. Signed-off-by: Timo Teras <timo.teras@solidboot.com> Signed-off-by: Juha Yrjola <juha.yrjola@solidboot.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2005-11-10[ARM] 3145/1: OMAP 3a/5: Add support for omap24xxTony Lindgren
Patch from Tony Lindgren This patch adds support for omap24xx series of processors. The files live in arch/arm/mach-omap2, and share common files with omap15xx and omap16xx processors in arch/arm/plat-omap. Omap24xx support was originally added for 2.6.9 by TI. This code was then improved and integrated to share common code with omap15xx and omap16xx processors by various omap developers, such as Paul Mundt, Juha Yrjola, Imre Deak, Tony Lindgren, Richard Woodruff, Nishant Menon, Komal Shah et al.
