Subject[PATCH 0/4 v6] drm: Add support of ARC PGU display controller
Date
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 (v6) that introduces drm_connector_register_all()
is a prerequisite now: https://lkml.org/lkml/2016/4/19/299

Changes v5 -> v6:
* "arc: Add our own implementation of fb_pgprotect()" was already applied to
ARC's tree and available in linux-next:
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=e5e0a65cd20a7a892a87e6bd73bdc3d83726d725

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.
