[PATCH v2 0/4] Exynos 5410 Dual cluster support

[Vyacheslav Tyrtov]

The series of patches represent support of Exynos 5410 SoC
    
The Exynos 5410 is the first Samsung SoC based on bigLITTLE architecture.
Patches allow all 8 CPU cores (4 x A7 and 4 x A15) to run at the same time
    
Patches add new platform description, support of clock controller,
dual cluster support and device tree for Exynos 5410 
   
Has been build on v3.12-rc5.
Has been tested on Exynos 5410 reference board (exynos_defconfig).
    
Thanks,
	Vyacheslav.


Changelog:

v2:
	In drivers/clk/samsung/clk-exynos5410.c
1. Clock driver converted to use preprocessor macros instead of enums.
   Clock IDs now defined in include/dt-bindings/clock/exynos5410.h.
2. Unused spinlock removed.
3. Function exynos5410_clk_init defined as static.
   Struct exynos5410_fixed_rate_ext_clks defined as static.
   Struct exynos5410_mux_clks defined as static.
   Struct exynos5410_div_clks defined as static.
   Struct exynos5410_gate_clks defined as static.
4. Removed aliases.
5. Pll's magic register offsets defined as preprocessor macros.
6. Redundant check of device_node pointer removed.
	
	In arch/arm/boot/dts/exynos5410.dtsi
1. dwmmcX nodes renamed to mmc.
   dwmmc_X renamed to mmc_X.
   dwmmc status="disabled" field added.
   fifo-depth field moved from arch/arm/boot/dts/exynos5410-smdk5410.dts
2. Blank lines added where necessary.
3. cpu@ suffixes corrected.
4. edcs node removed.
5. Hexadecimal characters case corrected.
6. Clock IDs replaced with preprocessor macros.
	
	In arch/arm/boot/dts/exynos5410-smdk5410.dts
1. status = "okay" field added to mmc nodes.
	
	In arch/arm/mach-exynos/edcs.c
1. "kfs_" prefix replaced with "edcs_"
2. EDCS_CPUS_PER_CLUSTER and EDCS_CLUSTERS defined instead of MCPM's values.
3. Cache handling sequence borrowed from arch/arm/mach-vexpress/tc2_pm.c
4. mcpm_sync_init() call added.
5. power management functions reworked.
	
	Other
1. Documentation/devicetree/bindings/clock/exynos5410-clock.txt corrected.
2. Removed smdk5410_defconfig. Instead SOC_EXYNOS5410 now selects MCPM and
   ARM_CCI in arch/arm/mach-exynos/Kconfig.
3. edcs_status driver removed.
