Linus Torvalds 21604cdcdc ARM: SoC cleanups for 3.13
This branch contains code cleanups, moves and removals for 3.13.
 
 Qualcomm msm targets had a bunch of code removal for legacy non-DT
 platforms. Nomadik saw more device tree conversions and cleanup of old
 code. Tegra has some code refactoring, etc.
 
 One longish patch series from Sebastian Hasselbarth changes the init_time
 hooks and tries to use a generic implementation for most platforms,
 since they were all doing more or less the same things.
 
 Finally the "shark" platform is removed in this release. It's been
 abandoned for a while and nobody seems to care enough to keep it
 around. If someone comes along and wants to resurrect it, the removal
 can easily be reverted and code brought back.
 
 Beyond this, mostly a bunch of removals of stale content across the
 board, etc.
