Merge tag 'renesas-r8a7779-multiplatform-for-v3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc
Pull "Renesas ARM Based SoC r8a7779-multiplatform Updates for v3.17" from
Simon Horman:
Move r8a7779 SoC and its Marzen board to use common clocks,
multiplatform and initialise SCIF (serial) devices using DT.
