Video driver for older Allwinner SoCs uses cfb console framework which in turn uses struct ctfb_res_modes to hold timing informations. However, DM video framework uses different structure - struct display_timing. It makes more sense to convert lcdc to use new timing structure because all new drivers should use DM video framework and older drivers might be rewritten to use new framework too.
