What would be your suggestion to > move on (dtb overlays) ? The solution we use for the ZII RDU1 and RDU2 boards is to have the bootloader patch in the correct panel compatible strings. This is quite a bit simpler than using overlays and if you already have a environment variable for this it should be easy to do. > > > > Shawn > > > > > + > > > +&ldb { > > > + lvds0: lvds-channel@0 { > > > + fsl,data-mapping = "spwg"; > > > + fsl,data-width = <24>; > > > + }; > > > +}; This isn't needed. The panel compatible implies the data mapping and bus width (at least if you properly filled in this information in the panel driver).
