This patch series is a part of continuation work from following series
[1] and [2].
1: exynos: Move pmu driver to driver/soc folder and add exynos7 support
http://www.spinics.net/lists/linux-samsung-soc/msg39797.html from Amit Daniel Kacchap
2: soc: samsung: pmu: split up SoC specific PMU data
https://lkml.org/lkml/2015/1/7/12 from me
Here is another attempt for the same, 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.
I have tested on Peach-Pi (Exynos5880) based chromebook for boot
and S2R functionality.
These patches have been prepared on top of Kukjin Kim's for-next
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

commit 6ec4f8d0d91f ("ARM: EXYNOS: add generic function to calculate
cpu number") introduced exynos_pmu_cpunr to be used by multi-cluster SoC's
e.g Exynos5420, but it's no more used in the codebase and hence removing
this part of code.

Moving Exynos PMU specific header file into "include/linux/soc/samsung"
thus updated affected files under "mach-exynos" to use new location of
these header files.

This patch splits up mach-exynos/pmu.c file, and moves exynos3250 PMU
configuration data and functions handing those data into exynos3250
SoC specific PMU file mach-exynos/exynos3250-pmu.c.

This patch splits up mach-exynos/pmu.c file, and moves exynos4210,
exynos4412 and exynos4212 PMU configuration data and functions handing
data into a common exynos4 SoC specific PMU file mach-exynos/exynos4-pmu.c.

This patch splits up mach-exynos/pmu.c file, and moves exynos5250,
PMU configuration data and functions handing data into exynos5250
SoC specific PMU file mach-exynos/exynos5250-pmu.c.

This patch splits up mach-exynos/pmu.c file, and moves exynos5420,
PMU configuration data and functions handing data into exynos5420
SoC specific PMU file mach-exynos/exynos5420-pmu.c.

This patch moves Exynos PMU driver implementation from "arm/mach-exynos"
to "drivers/soc/samsung". This driver is mainly used for setting misc
bits of register from PMU IP of Exynos SoC which will be required to
configure before Suspend/Resume. Currently all these settings are done
in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC
support, there is a need of this PMU driver in driver/* folder.
This driver uses existing DT binding information and there should
be no functionality change in the supported platforms.

No changes in file, don't touch the copyright date.
Instead please update the header-inclusion guard:
__SOC_EXYNOS_PMU_H

These shouldn't be static inlines in header because you will duplicate
it in each compiled object. Leave optimizations to compiler.
Rest looks good,

+Cc Bartlomiej,
There were some concerns for previous versions of this patchset. I
cannot find all of them (e.g. Bartlomiej's are not present on lkml.org
anymore) so I am not sure if they were addressed properly.
I like the approach, it helps in reviewing the patch.
I wonder - after adding this for ARM64 how much of duplicated code this
approach reduce?
Best regards,
Krzysztof

This should be rebased on:

1. Please reorder the exynos_sys_powerdown_conf() to be after the
statics. I am thinking also about adding EXPORT_SYMBOL... but maybe this
would be over-thinking.
2. I think the proper location of everything is drivers/power/reset/.
Although I don't have strong opinion.
3. Please cc linux-pm and arm-soc guys (Arnd, Olof, Kevin) on next
iteration.
Best regards,
Krzysztof

Yes. If I recall correctly he has following main concerns:
1: To convert exynos-pmu to a proper platform driver before moving out
of arch/arm/mach-exynos. This is already addressed.
2: Do we really need common driver for both ARM and ARM64? I feel yes,
as at least I can see that driver's basic structure will be reused. As
in case of PMU driver most of lines of code is data part (register
offset and its values in different mode), that part will be kept in
separate file e.g. exynos7-pmu.c or exynosXXXX-pmu.c.
There has been already one attempt of submission for exynos7 PMU driver at:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/305418.html
3: He had a concern that in case of ARM64 build most of ARM related code
will be present in binary which will be dead code, that can be addressed
by excluding ARM based SoC exynosXXXX-pmu.c file in Makefile.
It has been taken care in v3 7/7 patch in drivers/soc/samsung/Makefile.

Thanks. This was a review comment from Kukjin, to separate data part of
all SoC and move them to respective files, same as we do for clock files
of each SoC.

It will reduce in duplication driver structure, which will be same.

There has been discussion about the proper location for this driver,
initial attempt was done in "drivers/mfd" folder but then we realized
that this driver is not exactly fitting in MFD category.
There was suggestion from Catalin Marinas [1], [2] to move it to
"drivers/power" or a more suitable place other than mfd. As I received
comments from Bartlomiej [3] and other members also (sorry I could not
produce all links as it was quite more than a year back), I feel driver
is very much SoC specific and hence decided to move it here.

Sounds reasonable to me. Maybe someone will have other comments but for
me it's okay. When sending next version, please CC linux-pm mailing list
and arm-soc maintainers (Arnd, Olof, Kevin).

Usually static functions are put at beginning of a file and the
externally linkable ones (including exportable) are at the end. This
allows quick finding of what is exported by this unit.
Mixing static-nonstatic-static brings confusion/
This is a driver so everything except it is static, so I see two choices:
1. Put it in front, just after pmu_context definition.
2. Put it in back, just before the probe.

In drivers/power/reset there are already very-SoC-specific reset
handlers. All of them are non-reusable outside of some SoC family.
However I don't think it really matters - both locations (soc and power)
seem fine to me.
Looking at Bart's comments I see that you did not resolve all of them.
One was left:
"what happens if exynos_sys_powerdown_conf() is called
while there are no platform devices binded to a driver but driver itself
is loaded."
Looking at the code NULL pointer exception will happen on pmu_context
dereference.
Best regards,
Krzysztof
