And let's be realistic, how many MX23/MX28 users of old DTs with new kernels are there who cannot update the DT as well ? IMO keeping the old FBDEV driver in is just an excuse to postpone the long overdue DT update and I dislike that. Update any remaining DTs and nuke the FBDEV driver already. -- Best regards, Marek Vasut -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
