Rebased on
1] Kukjin Kim's tree for-next branch (which has Sachin Kamat's SYSRAM
patches merged) with Tomasz Figa's samsung clock tree (samsung-next branch)
merged.
https://git.kernel.org/cgit/linux/kernel/git/kgene/linux-samsung.git/log/?h=for-next
2] Pankaj Dubey's v4 PMU patchset
https://lkml.org/lkml/2014/5/10/29
Pankaj's patches have the following dependencies:
[1] mfd: syscon: Support early initialization
https://lkml.org/lkml/2014/4/8/239
[2] Daniel Lezcano's Exynos cpuidle refactor patches
http://thread.gmane.org/gmane.linux.kernel.samsung-soc/29085
[3] Allow NULL property in syscon_early_regmap_lookup_by_phandle
https://lkml.org/lkml/2014/5/10/10 and
https://lkml.org/lkml/2014/4/29/661
Note: Some of the above patches did not apply cleanly on Kgene's for-next
branch.
