Linus Torvalds da06a8d7be ARM: SoC fixes 
A series of fixes (and in some cases, some cleanups):
 
 Via Tony Lindgren:
 - A collection of OMAP regression fixes, in particular because firmware
   no longer sets up all pin states before starting the kernel.
 - cpufreq fixes for OMAP (Rafael is on vacation and this was pre-agreed).
 - A longer series of misc regression fixes and cleanups, warning removals,
   etc for OMAP
 
 From Arnd Bergmann:
 - A series of warning fixes for various platforms (defconfig builds)
 
 Misc:
 - A couple of tegra fixes, one for i.MX, some vt8500 fixes, etc.
