Merge tag 'drivers-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver changes from Arnd Bergmann:
"These changes are mostly for ARM specific device drivers that either
don't have an upstream maintainer, or that had the maintainer ask us
to pick up the changes to avoid conflicts.
A large chunk of this are clock drivers (bcm281xx, exynos, versatile,
shmobile), aside from that, reset controllers for STi as well as a
large rework of the Marvell Orion/EBU watchdog driver are notable"
