Merge branch 'drm-armada-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into...

* remove support for the non-component support from the Armada DRM driver,
  switching it to component-only mode.
* create a "armada plane" to allow the primary and overlay planes to share
  some code.
* increase efficiency by using inherently atomic operations, rather than
  spinlocking to achieve atomicity.  Eg, if we want to exchange a value,
  using xchg().
* increase PM savings by stopping the external pixel clock when we're in
  DPMS mode.
