[PATCH v6 0/9] samsung: pmu: split up SoC specific PMU data

From: Pankaj Dubey
Date: Tue Nov 17 2015 - 01:09:38 EST


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.dubey@xxxxxxxxxxx>

For testing entire patchset on on Trats2 (Exynos4412, S2R, reboot, poweroff)
and Odroid XU3 (Exynos5422, reboot, poweroff).

Tested-by: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx>

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
