2011-09-21ARM: SAMSUNG: Update the name of regarding Samsung GPIOKukjin Kim
According to gpio-samsung.c, this patch updates the name of regarding Samsung GPIO. Basically the samsung_xxx prefix is used in gpio-samsung.c instead of s3c_xxx, because unified name can reduce its complexity. Note: some s3c_xxx stil remains because it is used widely. It will be updated next time. Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2011-07-20ARM: SAMSUNG: Add support for pre-sleep/post-restore gpio controlBen Dooks
Add a callback so that per-arch can do pre-sleep and post-resume gpio configuration so that for the S3C64XX, the GPIO configuration is restored before the sleep mode is cleared. For the S3C64XX case, it means that the GPIOs get set back to normal operation after the restore code puts the original configurations back in after the Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-07-02ARM: pm: allow suspend finisher to return error codesRussell King
There are SoCs where attempting to enter a low power state is ignored, and the CPU continues executing instructions with all state preserved. It is over-complex at that point to disable the MMU just to call the resume path. Instead, allow the suspend finisher to return error codes to abort suspend in this circumstance, where the cpu_suspend internals will then unwind the saved state on the stack. Also omit the tlb flush as no changes to the page tables will have happened. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-06-24ARM: pm: hide 1st and 2nd arguments to cpu_suspend from platform codeRussell King
The first and second arguments shouldn't concern platform code, so hide them from each platforms caller. Tested-by: Kevin Hilman <khilman@ti.com> Acked-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-06-24ARM: pm: samsung: move cpu_suspend into C codeRussell King
Move the call to cpu_suspend into C code, and noticing that all the s3c_cpu_save implementations are now identical, we can move this into the common samsung code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-06-24ARM: pm: move cpu_init() call into core codeRussell King
As we have core code dealing with CPU suspend/resume, we can re-initialize the CPUs exception banked registers via that code rather than having platforms deal with that level of detail. So, move the call to cpu_init() out of platform code into core code.

2011-04-14ARM: SAMSUNG: Fix warning 's3c_pm_show_resume_irqs' defined but not usedMaurus Cuelenaere
s3c_pm_show_resume_irqs() is used by some s3c_pm_arch_show_resume_irqs() implementations, which get included through mach/pm-core.h.

2010-12-30ARM: SAMSUNG: Convert s3c_irqext_wake() to new irq_ interrupt methodsMark Brown
Kernel 2.6.37 adds new interrupt methods which take a struct irq_data rather than an irq number. Begin converting Samsung platforms over to these methods by converting s3c_irqext_wake() with a simple textual substitution.

2010-11-16suspend: constify platform_suspend_opsLionel Debroux
While at it, fix two checkpatch errors. Several non-const struct instances constified by this patch were added after the introduction of platform_suspend_ops in checkpatch.pl's list of "should be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73). Patch against mainline. Inspired by hunks of the grsecurity patch, updated for newer kernels.
