This series add support of ARC PGU display controller.
ARC PGU is a quite simple byte streamer that gets data from the framebuffer
and pushes it to hte connected encoder (DP or HDMI).
It was tested on ARC SDP boards (axs101/103 in particular).
Note following series that introduces
drm_connector_register_all()/drm_connector_unregister_all() is a prerequisite
now: https://lkml.org/lkml/2016/3/23/61
Changes v4 -> v5:
* Removed encode node from DT bindings example (as suggested by Rob)
Changes v3 -> v4:
* Main driver author is now set properly (thanks Carlos for all your efforts)
* Implemented correct hsync and vsync setup (thanks Jose)
* Dummy call-backs were removed (as suggested by Daniel)
* Obsolete load()/unload() call-backs were removed (as suggested by Daniel)
* With above in mind we were able to adopt recently introduced
drm_connector_register_all()/drm_connector_unregister_all()
* Implemented setup of properties (uncached) for FB user-pages
* Minor clean-up in DT binding docs and axs10x_mb.dtsi
Changes v2 -> v3:
* Improved failure path if arcpgu_connector wasn't allocated.
* Fixed driver building as module.
* Implemented uncached mapping of user-space FB pages.
* Again updated DT bindings docs.
Changes v1 -> v2:
* Clean-up of DT bindings documentation.
* Added missing "pxlclk" clock in axs10x_mb.dtsi.
