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

Pull ARM SoC late changes from Olof Johansson:
 "We were expecting to sit on this branch through most of the merge
  window since the contents was merged into our tree late, but we ended
  up sitting on all of our contents so it can go in with the rest.

  The contents here is:

   - a large branch of cleanups of the CM/PRM blocks on OMAP.

   - a couple of patches plumbing up CM/PRM on OMAP5 and DRA7.

   - a branch with DT updates for Freescale i.MX.  including some
     shuffling from .dts to .dtsi (include) files that causes a little
     churn"

OMAP Control Module bindings



Control Module contains miscellaneous features under it based on SoC type.

Pincontrol is one common feature, and it has a specialized support

described in [1]. Typically some clock nodes are also under control module.

Syscon is used to share register level access to drivers external to

control module driver itself.



See [2] for documentation about clock/clockdomain nodes.
