Merge tag 'vexpress/drivers-for-3.9' of git://git.linaro.org/people/pawelmoll/linux into next/drivers
From Pawel Moll:
Versatile Express related driver updates for 3.9:
* Move sp810 header to a more generic location,
mainly to share it with arm64
* tag 'vexpress/drivers-for-3.9' of git://git.linaro.org/people/pawelmoll/linux:
arm: Move sp810.h to include/linux/amba/
+ Linux 3.8-rc5
