* | | sh: Kill off the remnants of the old timer code.Paul Mundt2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | Now with all of the TMU users moved over to the new TMU driver, and the old TMU driver killed off, the left-over infrastructure can go along with it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | | sh: remove old TMU driverMagnus Damm2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the old TMU driver (CONFIG_SH_TMU/timer-tmu.c) As replacement, select the sh_tmu driver with CONFIG_SH_TIMER_TMU and configure timer channel using platform data. If multiple TMU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_tmu.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

* | | sh: CMT platform data for sh7720/sh7721Magnus Damm2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds CMT platform data for sh7720 and sh7721. All 5 32-bit CMT channels unfortunately share a single IRQ. Both clockevent and clocksource support is enabled. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | sh: Always fixup unaligned userspace accesses on sh64.Paul Mundt2009-05-08
| | | | | | | | | | | | | | | | | | | | | | | | sh64 has traditionally had this configurable via a Kconfig option (CONFIG_SH64_USER_MISALIGNED_FIXUP). In practice it has never really been terribly useful to turn this off, so just get rid of the option entirely. We leave the sysctl around so we don't end up breaking existing root file systems, and to allow folks that really want this off to do so at their own risk.

* | sh: Drop dead rules from arch/sh/kernel/Makefile_64.Paul Mundt2009-05-08
| | | | | | | | | | | | | | | | Several of these options are specific to the SHcompact ISA and will need to be rewritten for SHmedia if they are to be supported at all. Drop the impossible rules for now. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | Now that all of the possible users for rtc_lock have gone away, it is no longer necessary to keep this lock definition around. This follows several other architectures that have either recently dropped it or never supported it in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | sh: Wire up GENERIC_CMOS_UPDATE for the platforms that need it.Paul Mundt2009-05-08
| | | | | | | | | | | | | | | | | | | | Now that everything has converted over to generic timekeeping, we need an alternate method for keeping the RTC updated for those platforms that are still using the rtc_sh_get/set_time pairs, presently limited to SH-03 and the Dreamcast. This wires up the GENERIC_CMOS_UPDATE hooks for those to maintain the same behaviour. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* | sh: Finish the sh64 migration off of ARCH_USES_GETTIMEOFFSET.Paul Mundt2009-05-08
| | | | | | | | | | | | | | | | This adds sh_tmu support to the SH-5 subtypes, which subsequently allows us to kill off time_64.c and use the now generic time_32.c. As a bonus, SH-5 now supports highres timers and tickless for the first time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
