Thanks to Russell we have Armada DRM driver but currently DT support for it is stalled in various discussions/improvements. We know there are issues with the whole DRM chain (si5351,lcd,tda998x) that are not easy to track down. To get at least some more code testing coverage, this patch set picks up some patches from Russell slightly reworked to allow Dove DT to register and use Armada DRM. The approach taken is based on what we did in the past for mach-dove to mach-mvebu/dove conversion: platform_devices are registered like it was before DT and quirks are added to allow to register the corresponsing device properly. Then we start removing each of the quirks incrementally. Russell currently has a quite huge gap [1,2,3] between his branch and mainline Linux, so this is a tiny step forward to closen the gap and free some of his time for more controversal discussion. Also, it will allow us to participate in those discussions as we'll be able to test them more easily. Patches 1-3 add DT binding docs and corresponding nodes for the LCD controllers found on Marvell Dove SoCs. The binding itself is considered stable and not likely to change in the future. Patch 4 then adds above platform_device registration for DRM driver to Dove DT based setup. Currently, we require to steal some CMA mem for the framebuffers, collect lcd resources, and clocks from different nodes. As soon as DT for DRM driver and component framework have settled, we can remove the quirks again. Patches are based on v3.16-rc1 and have been tested on DT SolidRun CuBox.
