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.
