Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM 32-bit SoC platform updates from Olof Johansson:
 "Most of the SoC updates in this cycle are cleanups and moves to more
  modern infrastructure:

   - Davinci was moved to common clock framework

   - OMAP1-based Amstrad E3 "Superphone" saw a bunch of cleanups to the
     keyboard interface (bitbanged AT keyboard via GPIO).

   - Removal of some stale code for Renesas platforms

   - Power management improvements for i.MX6LL"
