[PATCH 00/20] Armada DRM updates for 4.4

[Russell King - ARM Linux]

Here are my queued changes for the Armada DRM driver, for the upcoming
4.4 merge window.

These changes are about updating the driver to some of the more recent
DRM APIs, and removing the non-component support now that has
stabilised.  This results in all of armada_output and armada_slave
being removed, resulting in 460 lines of code removed from that change
alone.

Other changes include:

* moving more towards supporting DRM planes in a more generic way,
  thereby reducing the duplication between the primary and overlay
  planes.
* locking cleanups, more like locking removal, prefering inherently
  atomic operations (eg, xchg) instead of spinlocking.  This ultimately
  results in simpler and faster code.

I've been running these patches for a while and haven't noticed any ill
effects.

Posted for comment, if nothing is forthcoming, I'll send a pull request
to David in a week or so's time.  These patches are against v4.2, but
rebase to 4.3-rc3 without any fuss.
