Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree changes from Arnd Bergmann:
"These changes from 30 individual branches for the most part update
device tree files, but there are also a few source code changes that
have crept in this time, usually in order to atomically move over a
driver from using hardcoded data to DT probing.
A number of platforms change their DT files to use the C preprocessor,
which is causing a bit of churn, but that is hopefully only this once"
