This patch series tries to remove machine specific implementation
of Power Management Unit from "mach-exynos" to driver form.
In case of ARM32 we had machine folder such as "mach-exynos" but
moving forward with ARM64 SoC support we can not have any more such
machine folders, keeping that in mind we have planned to move PMU
implementation out of machine folder and give it driver form.
Since PMU binding already exist as "samsung, exynosxxx-pmu, syscon"
and Syscon driver is located under "drivers/mfd" we are moving
Exynos PMU driver under "drivers/mfd", but suggestions are welcome.
This patch series is based on kgene for-next and depends on following
patch series
1) ARM: Exynos: PMU cleanup and refactoring for using DT
http://www.mail-archive.com/[email protected]/msg27875.html
We have tested this driver for System boot and PMU initialization on Exynos5250
and Exynos5260 (with support of some internal patches).

1.7.10.4
From: Younggun Jang <[email protected]>
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 DT based
implementation of PMU driver.
This driver uses already existing DT binding information.

PMU support for ARM32 EXYNOS SoCs is heavily SoC dependent and there
is very little code shared between diffirent SoCs. Unless PMU setup
for Samsung ARM64 SoCs is similar to some existing ARM32 EXYNOS SoCs
it may be better to just add a separate PMU driver for Samsung ARM64
SoCs. IOW it would be best to show that this patch series is really
useful before merging it.
When it comes to the current patches it would be better to do changes
converting PMU support to be a platform driver first for the existing
arch/arm/mach-exynos/pmu.c file and then move+rename this file in
the separate patch. Currently the code changes are done at the same
time as the code movement which makes them difficult to review/verify.
There are also some minor issues with the new code:

devm_ioremap_resouce() return value should be checked for errors with
if (IS_ERR(pmu_data->regs))
return PTR_ERR(pmu_data->regs);

exynos*_pmu_init() methods should be void as they always return 0 and
the return value is ignored anyway.
Also they cannot be marked with __init as the driver probe function
itself is not marked with __init (it cannot be beacuse of possibility
of doing unbind/bind through sysfs).

This driver can be build as module now but:
- exynos_sys_powerdown_conf() is not exported
- there is no exynos_pmu_driver_exit()
Also it is not clear what happens if exynos_sys_powerdown_conf() is called
while there are no platform devices binded to a driver but driver itself is
loaded.

We think it will be useful, but I will consider your point of making driver
which should have common piece of code to address various EXYNOS SoCs.
We are working on it, once it takes some proper shape I will post details here.

While you are moving pmu.c from arch/arm/mach-exynos/ why NOT move
pm.c also along, with this we can completely get rid of is_soc_*()
checks. Please see comments [1] from Tomasz figa for my PMU series on
5420 and 5260.

We thought of it, but as you know "arch/arm/mach-exynos/pm.c" has a lot
of dependencies, not only on "mach/exynos" header files but also on "plat-samsung".
Also we need to decide proper location for pm.c, I can think for "drivers/soc",
what do you say?
Seeing that there is a significant amount of work, we decided to keep this work
as separate from pmu.c work. May be after this patch we can start work on it.

This patch series moves PMU implementation from "mach-exynos/pmu.c" to
"drivers/mfd/exynos-pmu.c". Patch v1 was posted as RFC [1].
In case of ARM32 we had machine folder such as "mach-exynos" but
moving forward with ARM64 SoC support we can not have any more such
machine folders, keeping that in mind we have planned to move PMU
implementation out of machine folder, so that common piece of code
can be reused.
This patch series is based on kgene for-next and depends on following
patch series
a) [PATCH v2 0/5] Add PMU node for Exynos SoCs
https://lkml.org/lkml/2014/4/25/216
b) [PATCH v2 00/10] ARM: Exynos: PMU cleanup and refactoring for using DT
https://lkml.org/lkml/2014/4/25/252
1) [RFC PATCH 0/2] Add support for Exynos PMU driver
https://lkml.org/lkml/2014/4/2/69
Changes since v1:
- Rebased on Kukjin Kim's for-next (3.15_rc1 tag)
- Added patch: Move PMU specific definitions from common.h
- Added patch: Move pmu specific header files under "linux/mfd/samsung"
- Removed patch: ARM: EXYNOS: remove arch specific PMU implementation
As suggested breaking down patches into smalled pieces for better review.
Also modified all changes in pmu.c under mach-exynos itself and then
prepared patches moving files from mach-exynos to "drivers/mfd"

1.7.10.4
From: Younggun Jang <[email protected]>
This patch moves PMU specific definitions into a new file
as exynos-pmu.h. This will help in making PMU implementation
independent of common.h header.

these header files.

1.7.10.4
This patch moves Exynos PMU driver implementation from
"arm/mach-exynos" to "drivers/mfd".
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 DT based
implementation of PMU driver.
This driver uses already existing DT binding information.
