In this series I am splitting up SoC specific PMU configuration data into mach-exynos folder itself, before moving all of them under drivers/soc/samsung/. Also instead of making all changes in single patch it has been broken into SoC specific patches to avoid large size of patch. With this approach there will not be unwanted big churns just after adding exynos-pmu under drivers/soc/samsung.
All these patches are just refactoring to keep minimal changes while moving exynos-pmu driver under drivers/soc/samsung/. Support for exynos7 PMU can be added on top of it, in such a manner that for ARM64 build, ARM related SoC's PMU will not get compiled and thus unnecessary increasing kernel image size. These patches have been prepared on top of Kukjin Kim's for-next merged with driver-samsung and on top of cherry-picked change from [1]. 1: ARM: EXYNOS: Constify local exynos_pmu_data structure https://lkml.org/lkml/2015/10/28/917 For testing entire patchset on Peach-Pi (Exynos5880) based chromebook for boot and S2R functionality. Tested-by: Pankaj Dubey <pankaj.du...@samsung.com> For testing entire patchset on on Trats2 (Exynos4412, S2R, reboot, poweroff) and Odroid XU3 (Exynos5422, reboot, poweroff). Tested-by: Krzysztof Kozlowski <k.kozlow...@samsung.com> Changes since v5: - Removed extra blank line from patch 5/9 and 6/9. - Modified soc/samsung/Kconfig for config EXNOS_PMU. Added depends on ARM. Changes since v4: - In v3 I missed to give -M flag to detect rename, which made patches hard to review, so resubmitting patches with rename detector flag. - Addressed review comments from Krzysztof. Changes since v3: - Keeping intact copyright dates in existing header files. - Addressed review comments from Krzysztof for v3. - Removing static inline function from exynos-pmu.h and keeping them in PMU driver. - Added new patch (2/9) for fixing potential null pointer reference in exynos_sys_powerdown_conf. - Added new patch (8/9) for rearranging static and non-static function for better readability. Changes since v2: - Removed Amit's Samsung id as it's no more valid. - Rebased on latest kgene tree. - Removed redundant code from regs-pmu.h Pankaj Dubey (9): ARM: EXYNOS: removing redundant code from regs-pmu.h ARM: EXYNOS: Fix potential NULL pointer access in exynos_sys_powerdown_conf ARM: EXYNOS: Move pmu specific headers under "linux/soc/samsung" ARM: EXYNOS: split up exynos3250 SoC specific PMU data ARM: EXYNOS: split up exynos4 SoC specific PMU data ARM: EXYNOS: split up exynos5250 SoC specific PMU data ARM: EXYNOS: split up exynos5420 SoC specific PMU data ARM: EXYNOS: rearrange static and non-static functions of PMU driver drivers: soc: Add support for Exynos PMU driver arch/arm/mach-exynos/Kconfig | 1 + arch/arm/mach-exynos/Makefile | 2 +- arch/arm/mach-exynos/exynos.c | 4 +- arch/arm/mach-exynos/mcpm-exynos.c | 2 +- arch/arm/mach-exynos/platsmp.c | 2 +- arch/arm/mach-exynos/pm.c | 4 +- arch/arm/mach-exynos/pmu.c | 1004 -------------------- arch/arm/mach-exynos/suspend.c | 4 +- drivers/soc/samsung/Kconfig | 4 + drivers/soc/samsung/Makefile | 2 + drivers/soc/samsung/exynos-pmu.c | 183 ++++ drivers/soc/samsung/exynos-pmu.h | 44 + drivers/soc/samsung/exynos3250-pmu.c | 175 ++++ drivers/soc/samsung/exynos4-pmu.c | 222 +++++ drivers/soc/samsung/exynos5250-pmu.c | 195 ++++ drivers/soc/samsung/exynos5420-pmu.c | 280 ++++++ .../linux/soc/samsung}/exynos-pmu.h | 6 +- .../linux/soc/samsung/exynos-regs-pmu.h | 15 +- 18 files changed, 1120 insertions(+), 1029 deletions(-) delete mode 100644 arch/arm/mach-exynos/pmu.c create mode 100644 drivers/soc/samsung/exynos-pmu.c create mode 100644 drivers/soc/samsung/exynos-pmu.h create mode 100644 drivers/soc/samsung/exynos3250-pmu.c create mode 100644 drivers/soc/samsung/exynos4-pmu.c create mode 100644 drivers/soc/samsung/exynos5250-pmu.c create mode 100644 drivers/soc/samsung/exynos5420-pmu.c rename {arch/arm/mach-exynos => include/linux/soc/samsung}/exynos-pmu.h (81%) rename arch/arm/mach-exynos/regs-pmu.h => include/linux/soc/samsung/exynos-regs-pmu.h (98%) -- 2.4.5 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
