This is a from-scratch driver targeting Verisilicon DC-series display controllers, which feature self-identification functionality like their GC-series GPUs. Only DC8200 is being supported now, and only the main framebuffer is set up (as the DRM primary plane). Support for more DC models and more features is my further targets. As the display controller is delivered to SoC vendors as a whole part, this driver does not use component framework and extra bridges inside a SoC is expected to be implemented as dedicated bridges (this driver properly supports bridge chaining).
