These are changes that arrived a little late before the merge
window or that have multiple dependencies on previous branches
so they did not fit into one of the earlier ones. There
are 10 branches merged here, a total of 39 non-merge commits.
Contents are a mixed bag for the above reasons:
* Two new SoC platforms: ST microelectronics stixxxx and
the TI 'Nspire' graphing calculator. These should have
been in the 'soc' branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos,
which is based on the other exynos branches to avoid
conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM
Conflicts:
* In Kconfig.debug, various additions trivially conflict,
the list should be kept in alphabetical order when
resolving.
