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 v3.13-rc1. Has been tested on Exynos 5410 reference board (exynos_defconfig). Thanks for all your comments to Tomasz Figa, Dave Martin and Nicolas Pitre. Vyacheslav. Changelog: v4: In arch/arm/mach-exynos/edcs.c 1. Renamed all exynos_ prefixes to edcs_. 2. Reworked edcs_core_power_up/down functions. 3. Removed exynos_core_power_control function. 4. Added this_core_to_pcpu function. 5. Added core_power_state function which detects if cpu is being reset. 6. Replaced cache flush sequences with v7_exit_coherency_flush(). 7. exynos_core_power_down moved to lock protected area. 8. edcs_power_down_finish implemented. In Documentation/devicetree/bindings/clock/exynos5410-clock.txt 1. External clocks documented. In arch/arm/boot/dts/exynos5410-smdk5410.dts 1. oscclk node corrected according to ePAPR recommendation. In arch/arm/boot/dts/exynos5410.dtsi 1. mct@101C0000 node renamed to timer@101C0000. 2. "interrupt-controller" line removed from mct node. 3. mct_map renamed to interrupt_map. In arch/arm/mach-exynos/Kconfig 1. some cosmetic corrections. In include/dt-bindings/clock/exynos5410.h 1. Unnecessary defines removed. v3: In drivers/clk/samsung/clk-exynos5410.c 1. Fixed rate clock "samsung,clock-oscclk" removed. In arch/arm/boot/dts/exynos5410.dtsi 1. In mct node clock CLK_FIN_PLL replaced with generic fixed rate oscclk. In arch/arm/boot/dts/exynos5410-smdk5410.dts 1. Fixed rate oscclk clock added. In arch/arm/mach-exynos/edcs.c 1. Added write memory barrier in exynos_core_power_control function. 2. __raw_readl/__raw_writel replaced with readl_relaxed/writel_relaxed. 3. #define added for some magic constants. 4. Disabled the GIC CPU interface in exynos_power_down function. 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.
