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 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.
