The max-width should be the hardware's maximum supported width, not used for bandwidth. tilcdc has max-bandwidth property for that. Tomi

It has been determined that the highest resolution supported correctly by LCDC rev1 is 800x600 on da850 due to memory bandwidth constraints. Set the max_width property in da850.dtsi to 800.
