This patch series attempts to get rid of soc_is_exynosXXXX macros and eventually with the help of this series we can probably get rid of CONFIG_SOC_EXYNOSXXXX in near future. Each Exynos SoC has ChipID block which can give information about SoC's product Id and revision number. Currently we have single DT binding information for this as "samsung,exynos4210-chipid". But Exynos4 and Exynos5 SoC series have one small difference in chip Id, with resepect to product id bit-masks. So it means we should have separate compatible string for these different series of SoCs. So I have created new binding information for handling this difference. Also currently I can think of putting this driver code under "drivers/misc/" but suggestions are welcome. Also current form of driver is missing platfrom driver and needs init function to be called from machine file (either exynos.c or platsmp.c). I hope lot of suggestions and comments to improve this further. This patch series is based on Kukjin Kim's for-next (3.14_rc1 tag) and prepared on top of following patch series and it's dependent patch series. : Map SYSRAM through generic SRAM bindings. http://www.spinics.net/lists/arm-kernel/msg327677.html : Exynos PMU cleanup and refactoring. https://lkml.org/lkml/2014/4/30/44 Pankaj Dubey (4): ARM: EXYNOS: remove soc_is_exynos4/5 from exynos.c ARM: EXYNOS: remove unused header inclusion from hotplug.c misc: exynos-chipid: Add Exynos Chipid driver support ARM: EXYNOS: Refactoring to remove soc_is_exynosXXXX macros from exynos .../bindings/arm/samsung/exynos-chipid.txt | 15 ++++ arch/arm/Kconfig | 1 + arch/arm/boot/dts/exynos4.dtsi | 2 +- arch/arm/boot/dts/exynos5.dtsi | 2 +- arch/arm/mach-exynos/exynos.c | 66 ++++++++-------- arch/arm/mach-exynos/hotplug.c | 2 - arch/arm/mach-exynos/platsmp.c | 10 ++- arch/arm/mach-exynos/pm.c | 28 +++---- arch/arm/plat-samsung/include/plat/cpu.h | 60 -------------- drivers/clk/samsung/clk-exynos4.c | 2 +- drivers/cpufreq/exynos-cpufreq.c | 9 +-- drivers/cpufreq/exynos-cpufreq.h | 1 - drivers/cpufreq/exynos4x12-cpufreq.c | 5 +- drivers/misc/Kconfig | 7 ++ drivers/misc/Makefile | 1 + drivers/misc/exynos-chipid.c | 83 ++++++++++++++++++++ include/linux/exynos-soc.h | 46 +++++++++++ 17 files changed, 215 insertions(+), 125 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/samsung/exynos-chipid.txt create mode 100644 drivers/misc/exynos-chipid.c create mode 100644 include/linux/exynos-soc.h -- 22.214.171.124 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to email@example.com More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
