Ok, I agree. Looking at the dts files, panel-dpi is used in a bunch of boards. But we even have 3 dts files with panel-dpi, without the detailed panel model in compatible... Fixing those will break the compatibility with old dtbs and new kernel, unless we add timings-from-dt to a panel driver that handles panel-dpi.
