Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/scottwood/linux into next
Freescale updates from Scott:
"Highlights include 64-bit book3e kexec/kdump support, a rework of the
qoriq clock driver, device tree changes including qoriq fman nodes,
support for a new 85xx board, and some fixes.
Note that there is a trivial merge conflict with the clock tree's next
branch, in the clock Makefile."
