2017-02-28ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbolFlorian Fainelli
All low-level PM/SMP code using virt_to_phys() should actually use __pa_symbol() against kernel symbols. Update code where relevant to move away from virt_to_phys().

2017-01-26pinctrl: samsung: Move retention control from mach-s5pv210 to the pinctrl driverMarek Szyprowski
This patch moves pad retention control from S5PV210 machine code to Exynos pin controller driver. This helps to avoid possible ordering and logical dependencies between machine and pin control code. Till now it worked fine only because sys_ops for machine code and pin controller were called in registration order.

This moves <mach/regs-clock.h> into mach-s5pv210 so no more include/mach/ under mach-s5pv210. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Cc: Tomasz Figa <t.figa@samsung.com>
2014-07-19ARM: S5PV210: Untie PM support from legacy codeTomasz Figa
This patch makes S5PV210 not rely on legacy suspend helpers in plat-samsung and implements platform suspend logic locally, similarly to Exynos. Signed-off-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2014-07-19ARM: S5PV210: Remove support for board filesTomasz Figa
Since all in-tree boards have been moved to device tree, we can now drop legacy code and make mach-s5pv210 DT-only. This patch does it. Signed-off-by: Tomasz Figa <t.figa@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2014-07-19ARM: SAMSUNG: Remove legacy clock codeTomasz Figa
Since S5PV210 now has a complete clock driver using Common Clock Framework, there is no reason to keep the old code. Remove it together with the whole legacy Samsung-specific clock framework which no longer has any users.

2013-08-12ARM: SAMSUNG: Remove remaining uses of plat/regs-timer.h headerTomasz Figa
This patch removes remaining inclusions of plat/regs-timer.h as a preparation to remove the header. As a part of this, things like save and restore of PWM registers are removed from SoC-specific code, because it is handled in appropriate drivers now.

2013-01-30ARM: SAMSUNG: Gracefully exit on suspend failureAbhilash Kesavan
As per the Exynos5250 User Manual: When there are pending interrupt events, WFI/WFE instruction are ignored. To cancel the power-down sequence follow these steps: 1) Disable system power-down using CENTRAL_SEQ_CONFIGURATION register 2) Clear WAKEUP_STAT register 3) Enable interrupt service routine for CPU Code for early wakeup for exynos already exists. Remove the panic on suspend failure, clear the wakeup state register and return 1 from cpu_suspend to indicate a failed suspend (to a user daemon). Older Samsung SoCs have similar panics and I have removed them all. Haven't touched the S3C2410 sleep code.

2012-01-27ARM: SAMSUNG: Fix missing api-change from subsys_interface changeHeiko Stuebner
Commit 4a858cfc9a (arm: convert sysdev_class to a regular subsystem) converted the samsung sysdevs into subsys_interface instances. While the original add-function only had a (struct sys_device *) parameter, the dev_add from subsys_interface needs (struct device *, struct subsys_interface *) leading to "initialized from incompatible pointer type" warnings.

After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.

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.
