Merge "ARM: rockchip: soc code changes for 4.1" from Heiko Stuebner:

Some suspend improvements reducing resume time and making sure the
watchdog does not reset after 12 hours and a change to constify and
staticize some smp parts.

* tag 'v4.1-rockchip-soc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip

:
