Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann:
"This time around, the cleanup branch contains mostly code removal. A
number of board files for at91, imx and msm have become obsolete
because of the DT conversion and are now ready to be removed. The
OMAP platform has traditionally had its own DMA engine abstraction and
as this is being phased out, a lot of the original code is now unused
and can be removed as well.
S3C24xx can be simplified now that the restart code is a proper device
driver.
Finally, a number of cleanups in shmobile are done to prepare for the
addition of new code in other branches"
