2013-02-03ARM: S3C24XX: Move irq syscore-ops to irq-pmHeiko Stuebner
With this the definition of s3c24xx_irq_syscore_ops can also move to common.h from plat/pm.h and the definitions of s3c24xx_irq_suspend and s3c24xx_irq_resume are also not necessary anymore in plat/pm.h Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

2011-12-21arm: convert sysdev_class to a regular subsystemKay Sievers
After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.

2011-12-09ARM: S3C64XX: Implement basic power domain supportMark Brown
The S3C64xx SoCs contain a set of gateable power domains which can be enabled and disabled at runtime in order to save power. Use the generic power domain code to implement support for these in software, enabling runtime control of most domains: - ETM (not supported in mainline). - Domain G: 3D acceleration (no mainline support). - Domain V: MFC (no mainline support). - Domain I: JPEG and camera interface (no mainline support). - Domain P: 2D acceleration, TV encoder and scaler (no mainline support) - Domain S: Security (no mainline support). - Domain F: LCD (driver already uses runtime PM), post processing and rotation (no mainline support). The IROM domain is marked as always enabled as we should arrange for it to be enabled when we suspend which will need a bit more work. Due to all the conditional device registration that the platform does wrap s3c_pm_init() with s3c64xx_pm_init() which actually puts the device into the power domain after the machines have registered, looking for platform data to tell if the device was registered. Since currently only Cragganmore actually sets up PM that is the only machine updated.

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>
2011-07-02ARM: 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: 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>
2011-04-24ARM / Samsung: Use struct syscore_ops for "core" power managementRafael J. Wysocki
Replace sysdev classes and struct sys_device objects used for "core" power management by Samsung platforms with struct syscore_ops objects that are simpler. This generally reduces the code size and the kernel memory footprint. It also is necessary for removing sysdevs entirely from the kernel in the future. Signed-off-by: Rafael J.

2011-02-11ARM: SAMSUNG: Ensure struct sys_device is declared in plat/pm.hMark Brown

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.
