Merge tag 'renesas-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM Renesas SoC cleanup, refactoring and more SMP support from Kevin Hilman:
"Lots of cleanup and refactoring and some SMP additions for Renesas
platforms. Due to some inter-dependencies with other arm-soc
branches, this Renesas stuff was separated out for sending after the
other branches were merged.
Highlights:
- remove unused board support and cleanup of unused headers
- refactoring of init and device registration
- simplify IRQ initialization"
