383acb0dac ARM: s5pv210: Remove legacy setting of external wakeup interrupts
Since Exynos/S5Pv210 pin-controller driver is taking care about setting
the external wakeup interrupts mask, the legacy code can be removed.

64fc2a947a ARM: 8641/1: treewide: Replace uses of virt_to_phys with __pa_symbol
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().

dabd145692 pinctrl: samsung: Move retention control from mach-s5pv210 to the pinctrl driver
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.

61cb263162 ARM: SAMSUNG: Remove remaining uses of plat/regs-timer.h header
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.

d3fcacf52d ARM: SAMSUNG: Gracefully exit on suspend failure
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.

04511a6fae ARM: SAMSUNG: Fix missing api-change from subsys_interface change
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.

bb072c3cf2 ARM / Samsung: Use struct syscore_ops for "core" power management
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.
