Merge tag 'ux500-multiplatform-mfd' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson
MFD portions of the ux500 multiplatform branch. A second tag for the ARM SoC tree will build upon this one. This mainly removes the header file dependencies from the PRCMU driver in the MFD subsystem, and moves the PM functions to the machine. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
