[GIT PULL] ARM: EXYNOS: Fixes and improvements for v4.2

[Krzysztof Kozlowski]

Dear Kukjin,


This groups important fixes and typical improvements for Exynos
SoC for next v4.2 merge window.

I hope you will find useful grouping these commits together.

Everything can be also found on github:
https://github.com/krzk/linux
Branches:
1. fixes-samsung
2. for-next-samsung


If you have any comments, do not hesitate as I would welcome any feedback.
I can also split it into separate fixes and normal updates if you want.


Description:
1. Fix second suspend to RAM on Trats2 board. This has shown up
   after enabling L2 cache but actually the "use delayed reset
   assertion" is to be blamed.
2. Fix imprecise external abort on Exynos5420 boards when exynos-dp
   driver tries to access the DP controller registers and the PD
   was turned off.
3. Various fixes for missing return checks in power domain code.
4. Fix RTC alarm on Arndale Octa board.
5. Improvements of reparenting clocks on power domain on/off.
6. Enabling S3C RTC on various boards.


Best regards,
Krzysztof
