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.

OK, will do as you suggested in next version.

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.
