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 in particular).
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.
