Merge tag 'devel' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
New feature development
This adds support for new features, and contains stuff from most
platforms. A number of these patches could have fit into other
branches, too, but were small enough not to cause too much
confusion here.
