2014-11-22ARM: EXYNOS: move restart code into pmu driverPankaj Dubey
Let's register restart handler from PMU driver for restart functionality. So that we can remove restart hooks from machine specific file, and thus moving ahead when PMU moved to driver folder, this functionality can be reused for ARM64 based Exynos SoC's.

2014-11-21ARM: EXYNOS: Add platform driver support for Exynos PMUPankaj Dubey
This patch modifies Exynos Power Management Unit (PMU) initialization implementation in following way: - Added platform driver support for Exynos PMU IP. - Added platform struct exynos_pmu_data to hold platform specific data. - For each SoC's PMU support now we can add platform data and statically bind PMU configuration and SoC specific initialization function. - Separate each SoC's PMU initialization function and make it as part of platform data. - It also removes uses of soc_is_exynosXYZ().

2014-07-23ARM: EXYNOS: Refactored code for using PMU address via DTPankaj Dubey
Under "arm/mach-exynos" many files are using PMU register offsets. Since we have added support for accessing PMU base address via DT, now we can remove PMU mapping from exynosX_iodesc. Let's convert all these access using iomapped address. This will help us in removing static mapping of PMU base address as well as help in reducing dependency over machine header files. Thus helping for migration of PMU implementation from machine to driver folder which can be reused for ARM64 based SoC. Also as we have removed static mappings from "regs-pmu.h" it does not need map.h anymore. But "platsmp.c" needed this and till now it got included indirectly. So lets move header inclusion of "mach/map.h" from "regs-pmu.h" to "platsmp.c".

2011-11-06ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynosKukjin Kim
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has made for plaforms based on EXYNOS4 SoCs. But since upcoming Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most codes in current mach-exynos4, one mach-exynos directory will be used for them. This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos) but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to avoid changing in driver side.
