2007-05-23sh: section mismatch fixes for system timer.Paul Mundt
Fix up a couple of section mismatch warnings regarding sys_timer. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-05-09sh: clockevent/clocksource/hrtimers/nohz TMU support.Paul Mundt
This adds basic support for clockevents and clocksources, presently only implemented for TMU-based systems (which are the majority of SH-3 and SH-4 systems). The old NO_IDLE_HZ implementation is also dropped completely, the only users of this were on TMU-based systems anyways. More work needs to be done to generalize the TMU handling, in that the current implementation is rather tied to the notion of TMU0 and TMU1 utilization. Additionally, as more SH timers switch over to this scheme, we'll be able to gut most of the remaining system timer infrastructure that existed before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-05-08Add IRQF_IRQPOLL flag on shBernhard Walle
Add IRQF_IRQPOLL on each timer interrupt on SH2.

2007-05-07sh: Add SH7785 Highlander board support (R7785RP).Paul Mundt
This adds preliminary support for the SH7785-based Highlander board. Some of the Highlander support code is reordered so that most of it can be reused directly. This also plugs in missing SH7785 checks in the places that need it, as this is the first board to support the CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Clock framework tidying.Paul Mundt
This syncs up the SH clock framework with the linux/clk.h API, for which there were only some minor changes required, namely the clk_get() dev_id and subsequent callsites. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Turn off IRQs around get_timer_offset() calls.Paul Mundt
Since all of the sys_timer sources currently do this on their own within the ->get_offset() path, it's more sensible to just have the caller take care of it when grabbing xtime_lock. Incidentally, this is more in line with what others (ie, ARM) are doing already. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Configurable timer IRQ.Paul Mundt
All of the various CPU subtypes currently hardcode TIMER_IRQ, switch this to a config option in the few places we need this. This allows further removal of hardcoded IRQ headers.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: SE7206 build fixes.Paul Mundt
A number of API changes happened underneath the 7206 patches, update for everything that broke. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Add support for SH7206 and SH7619 CPU subtypes.Yoshinori Sato
This implements initial support for the SH7206 (SH-2A) and SH7619 (SH-2) MMU-less CPUs. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-10-06sh: Updates for IRQ handler changes.Paul Mundt
Trivial fixes for build breakage introduced by IRQ handler changes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-10-06sh: Kill off timer_ops get_frequency().Paul Mundt
We're not using this anywhere these days, kill it off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Rename rtc_get/set_time() to avoid RTC_CLASS conflict.Paul Mundt
We have a clash with RTC_CLASS over these names, so we change them.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: APM/PM support.Andriy Skulysh
This adds some simple PM stubs and the basic APM interfaces, primarily for use by hp6xx, where the existing userland expects it. Signed-off-by: Andriy Skulysh <askulysh@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2006-01-16[PATCH] sh: Simple timer frameworkPaul Mundt
This builds on some of the clock framework code to support a simple system timer interface. Signed-off-by: Paul Mundt <lethal@linux-sh.org> Cc: john stultz <johnstul@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
