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.
