[GIT PULL] soc: samsung: Drivers for v4.11

[Krzysztof Kozlowski]

Hi,

Few changes in Exynos PMU driver including one that is needed by pinctrl
driver for runtime PM. We want to move forward with the RPM for our drivers
while keeping still DT ABI.


This tag is also for Linus Walleij to pull - base for pinctrl changes.

Best regards,
Krzysztof

----------------------------------------------------------------
Improvements for Exynos PMU driver for v4.11:

Beside basic function of setting proper configuration for low power modes, the
Exynos PMU (Power Management Unit) driver is also a provider of syscon regmap
for its registers.  This regmap is essential to many other drivers wanting to
or needing to implement low power mode.

Exynos pinctrl driver, before getting support for Runtime Power Management,
needs access to this syscon regmap.  Let's do it in a DT ABI friendly way.

Do I need it? I.e. will my branch not compile without this, or is this
just a runtime problem?

"[PATCH v3 11/13] pinctrl: samsung: Move retention control from 
mach-exynos to the
pinctrl driver" has compile time dependency on the changes included in 
that tag.

Is that because of the custom syscon regmap lookup function?

I just complained about that in a separate mail ;)

OK I pulled it and applied the final three patches from Marek
on top.

Grrr I was based in v4.10-rc1, well I could easily merge in v4.10-rc2
so no big deal.

Let's see if it survives linux-next.

Yours,
Linus Walleij

Sorry for that but it is all because of broken ARMv8 build at rc1.

Thanks for merging,
Krzysztof

Merged here as well.
