git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/cleanup3 Merge "Samsung PM related 2nd updates for v3.15" from Kukjin Kim: From Tomasz Figa <t.figa@samsung.com>: Current Samsung PM code is heavily unprepared for multiplatform systems. The design implies accessing functions and global variables defined in particular mach- subdirectory from common code in plat-, which is not allowed when building ARCH_MULTIPLATFORM. In addition there is a lot of forced code unification, which makes common function handle any possible quirks of all supported SoCs. In the end this design turned out to not work too well, ending with a lot of empty functions exported from mach-, just because code in common pm.c calls them. Moreover, recent trend of moving lower level suspend/resume code to proper drivers, like pinctrl or clk, made a lot of code there redundant, especially on DT-only platforms like Exynos.

2014-03-21ARM: EXYNOS: Fix compilation error in cpuidle.cTomasz Figa
The big series refactoring Exynos suspend to RAM handling missed the cpuidle driver that is disabled in exynos_defconfig, leaving it including old mach/pm_core.h header and using old s3c_cpu_resume symbol instead of new exynos_cpu_resume, resulting in compilation failures with CONFIG_ARCH_EXYNOS and CONFIG_CPU_IDLE enabled.

2014-03-21ARM: EXYNOS: Stop using legacy Samsung PM codeTomasz Figa
Since Exynos SoCs does not follow most of the semantics of older SoCs when configuring the system to enter sleep, there is no reason to rely on the legacy Samsung PM core anymore.

CONFIG_PM means that at least one of CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME is enabled, while multiple entries in mach-exynos/Kconfig abused it to enable sleep- and runtime-specific functionality.

2014-03-21ARM: SAMSUNG: Save UART DIVSLOT register based on SoC typeTomasz Figa
The only SoC that does not have DIVSLOT register is S3C2410, so instead of exporting a variable for platforms to set if DIVSLOT register should be preserved, it's enough to simply check whether we are running on a S3C2410 instead.

Due to the S3C2410 SoC being quite different from other S3C24xx SoCs in some aspects, such as availability of DIVSLOT register in its UART blocks, there is a need sometimes to check whether we are running on this SoC, not just the S3C24xx series.
