This adds support for the Armada 510 display subsystem found on the Marvell Dove devices. This IP is re-used across several different Marvell SoCs with various tweaks, and this driver has been structured to allow the other IPs to re-use the bulk of this code; further work in this area is expected from interested parties. This has been extensively tested on the SolidRun Cubox platform and appears to work well there. [airlied: update for api changes merged previous to this]
