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: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The RTC_LIB helpers are used in arch/sh/kernel/time.c, which was previously only the case for the 32-bit variant. Now that this has become the common implementation, move the RTC_LIB select to reflect that. Fixes up the sh64 build. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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: NPaul Mundt <lethal@linux-sh.org>

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: NPaul Mundt <lethal@linux-sh.org>

This patch adds a TMU driver for the SuperH architecture. The TMU driver is a platform driver with early platform support to allow using a TMU channel as clockevent or clocksource during system bootup or later. Clocksource or clockevent can be selected.

This patch removes the old MTU2 driver (CONFIG_SH_MTU2/timer-mtu2.c) As replacement, select the sh_cmt driver with CONFIG_SH_TIMER_MTU2 and configure timer channel using platform data. If multiple MTU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_mtu2.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

This patch adds a MTU2 driver for the SuperH architecture. The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.

This adds in support for building with ARCH=sh64 using the sh SRCARCH. This tidies up the randconfig generation somewhat to make sure that we don't end up with impossible configurations, and without having to rely on things like KCONFIG_ALLCONFIG to detect the proper CPU support subset.

Add kexec jump support to the SuperH architecture. Similar to the x86 implementation, with the following exceptions: - Instead of separating the assembly code flow into two parts for regular kexec and kexec jump we use a single code path. In the assembly snippet regular kexec is just kexec jump that never comes back. - Instead of using a swap page when moving data between pages the page copy assembly routine has been modified to exchange the data between the pages using registers. - We walk the page list twice in machine_kexec() to do and undo physical to virtual address conversion.

This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores that implement the PTAEX register and respective functionality. Presently only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs). The main change is in how the PTE is written out when loading the entry in to the TLB, as well as in how the TLB entry is selectively flushed. While SH-X2 extended mode splits out the memory-mapped U and I-TLB data arrays for extra bits, extended ASID mode splits out the address arrays. While we don't use the memory-mapped data array access, the address array accesses are necessary for selective TLB flushes, so these are implemented newly and replace the generic SH-4 implementation. With this, TLB flushes in switch_mm() are almost non-existent on newer parts. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch contains CONFIG_SUSPEND support to the SuperH architecture. If enabled, SuperH Mobile processors will register their suspend callbacks during boot. To suspend, use "echo mem > /sys/power/state". To allow wakeup, make sure "/sys/device/platform/../power/wakeup" contains "enabled". Additional per-device driver patches are most likely needed.

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).

SuperH CMT clockevent driver. Both 16-bit and 32-bit CMT versions are supported, but only 32-bit is tested. This driver contains support for both clockevents and clocksources, but no unregistration is supported at this point. Works fine as clock source and/or event in periodic or oneshot mode. Tested on sh7722 and sh7723, but should work with any cpu/architecture. This version is lacking clocksource and early platform driver support for now - this to minimize the amount of dependencies.

Fix up the build for mach-highlander and mach-rsk. These operated on the assumption that GENERIC_GPIO support with an optional GPIOLIB was possible. This used to be true, but has not been the case since commit-id d56cc8bc661ac1ceded8d45ba2d53bb134fee17d ("sh: use gpiolib"), where the GENERIC_GPIO implementation was rewritten to use GPIOLIB directly.
