* sh: Rename arch/sh/kernel/time_32.c to arch/sh/kernel/time.c.Paul Mundt2009-05-081-231/+0
| | | | | | | This is now fully generic, and used both by _32 and _64 variants. Rename it accordingly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off the now unused ARCH_USES_GETTIMEOFFSET code.Paul Mundt2009-05-031-9/+0
| | | | | | | | | Now that the stragglers (MTU2/CMT/etc.) have been rewritten and we are selecting both GENERIC_TIME and GENERIC_CLOCKEVENTS, the get_offset() timer op is completely unused. As a result, we are now able to kill off the ARCH_USES_GETTIMEOFFSET references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* time: sh: convert to use arch_getoffset() infrastructurejohn stultz2009-05-031-58/+5
| | | | | | | | Convert sh to use GENERIC_TIME via the arch_getoffset() infrastructure. Signed-off-by: John Stultz <johnstul@us.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: register the rtc-generic platform device properly.Paul Mundt2009-04-281-1/+16
| | | | | | | | The device registration was accidentally omitted, add it back in. Do some basic device probing as well, so this doesn't show up for platforms that tie in to the RTC interface properly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: setup timers in late_time_init()Magnus Damm2009-04-281-14/+20
| | | | | | | | | | | | | | This patch moves the SuperH timer setup code from time_init() to late_time_init(). Good things about this change: - interrupts: they are enabled at late_time_init() - mm: regular kmalloc() can be used at late_time_init() Together with moving to late_time_init() this patch changes the sh_cmt driver to always allocate with kmalloc(). This simplifies the code a bit and also fixes section mismatches. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: rtc-generic support.Paul Mundt2009-04-271-0/+23
| | | | | | This adds rtc-generic support for SUPERH32. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass clocksource pointer to the read() callback for clocksources. This allows us to share the callback between multiple instances.

* | sh: arch earlytimer supportMagnus Damm2009-04-191-0/+9
|/ | | | | | | | | | Extend the 32-bit SuperH timer code to register and probe the earlytimer class of Early Platform Drivers. This registers the sh_cmt driver if compiled-in. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Don't enable GENERIC_TIME for the CMT clockevent driver yet.Paul Mundt2009-01-291-2/+0
| | | | | | | | | GENERIC_TIME still depends on the clocksource bits being there, which is presently not supported. This allows the CMT clockevent driver to be used alongside alternate system timers that do not yet provide a clocksource of their own (MTU2 and so on in the case of SH-2A). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: fix no sys_timer caseMagnus Damm2009-01-291-1/+9
| | | | | | | Handle the case with a sys_timer set to NULL. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: rework clocksource and sched_clockMagnus Damm2009-01-291-50/+9
| | | | | | | | | | Rework and simplify the sched_clock and clocksource code. Instead of registering the clocksource in a shared file we move it into the tmu driver. Also, add code to handle sched_clock in the case of no clocksource. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off mv_heartbeat() from the machvec.Paul Mundt2008-12-221-5/+0
| | | | | | | Nothing is using this any more, so get rid of it before anyone gets the bright idea to start using it again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Generic kgdb stub support.Paul Mundt2008-12-221-7/+0
| | | | | | | | This migrates from the old bitrotted kgdb stub implementation and moves to the generic stub. In the process support for SH-2/SH-2A is also added, which the old stub never provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Early dummy clockevent registration on boot CPU.Paul Mundt2008-09-081-3/+4
| | | | | | | | The dummy timer needs to be registered on the boot CPU before the system timer clockevent is registered, or broadcasting doesn't work as advertized. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: generic clockevent broadcast support.Paul Mundt2008-09-081-2/+7
| | | | | | | | This hooks up GENERIC_CLOCKEVENTS_BROADCAST and a dummy local timer, which we call in to from the timer IPI when no other local timer is provided. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh/kernel/ cleanupsAdrian Bunk2008-07-281-1/+1
| | | | | | | | | | | | | | | | | This patch contains the following cleanups: - make the following needlessly global code static: - cf-enabler.c: cf_init() - cpu/clock.c: __clk_enable() - cpu/clock.c: __clk_disable() - process_32.c: default_idle() - time_32.c: struct clocksource_sh - timers/timer-tmu.c: struct tmu_timer_ops - remove the following unused functions (no CONFIG_BLK_DEV_FD on sh): - process_{32,64}.c: disable_hlt() - process_{32,64}.c: enable_hlt() Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
