[GIT PULL] ARM: EXYNOS: Improvements for 4.2, try 2

[Krzysztof Kozlowski]

Dear Kukjin,

Updated pull request. The first one contained an older version
of my patch.

This adds coupled cpuidle for Exynos3250 and improves the Exynos
code in few places. Everything for upcoming 4.2 merge window.
Description along with a tag.

Best regards,
Krzysztof

  ARM: plat-samsung: Constify platform_device_id (2015-05-06 11:05:43 +0900)

----------------------------------------------------------------
Extending cpuidle driver and improvements for Exynos based boards:
1. Add missing return-value checks and of_node_put() for power domain
   driver.
2. Fix missing clk_prepare in S3C24XX ADC driver.
3. Rework clock handling when switching power domains on/off. Instead
   of settting fixed parent in DTS we grab the parent clock before
   turning the domain off.
4. Add coupled cpuidle support for Exynos3250 to an existing
   cpuidle-exynos driver. As a result it enables AFTR mode
   (ARM-Off Top-Running) to be used by default on Exynos3250
   without the need to hot unplug CPU1 first.

Hi Krzysztof,

Firstly, thanks for your gentle reminder and effort.

By the way, this cannot be pulled because some of them are old patches
even though I've missed them at that time. Sorry about that and if it is
required, it should be re-submitted based on latest mainline after
testing then reviewed in ml again...

And please do use 'git am' or some relevant git commend when applying
patches in your tree because I found there are some comments below '---'
in git log such as 'changes since' or some 'note' but that is not
required. Just it is for information in ml not git log basically.

Anyway I'm going to sort them out including your patches in my tree
directly for 4.2.

Thanks again,
Kukjin

They were rebased on mainline. However some of them (cpuidle) depend
on "ARM: EXYNOS: Fix failed second suspend on Exynos4".

Right, this happened only for my patches which I cherry-picked thus
leaving the separator. Next time I will be more careful.

Thanks!
