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

           Say yes here if you have TWL4030 / TWL6030 family chip on your board.
           This core driver provides register access and IRQ handling
