Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Olof Johansson:
"This merge window brings a good size of cleanups on various platforms.
Among the bigger ones:
- Removal of Samsung s5pc100 and s5p64xx platforms. Both of these
have lacked active support for quite a while, and after asking
around nobody showed interest in keeping them around. If needed,
they could be resurrected in the future but it's more likely that
we would prefer reintroduction of them as DT and
multiplatform-enabled platforms instead.
- OMAP4 controller code register define diet. They defined a lot of
registers that were never actually used, etc.
- Move of some of the Tegra platform code (PMC, APBIO, fuse,
powergate) to drivers/soc so it can be shared with 64-bit code.
This also converts them over to traditional driver models where
possible.
- Removal of legacy gpio-samsung driver, since the last users have
been removed (moved to pinctrl)
Plus a bunch of smaller changes for various platforms that sort of
dissapear in the diffstat for the above. clps711x cleanups, shmobile
header file refactoring/moves for multiplatform friendliness, some
misc cleanups, etc"
