FWIW I've tested DRM PL111 driver on my board, if you are interested the pending DT patch is https://patchwork.kernel.org/patch/10636591/ Thank you for the changes, I'll review and collect them for v4.22. -- Best wishes, Vladimir

OK feel free to use however you like or use your own patches, all I really want is the PL11x DRM driver to become default for all platforms using PL11x. Will send LPC32xx patches next. Same thing there, use it if you like, all I worry about is the end result :) Yours, Linus Walleij

None of the LPC18xx device trees contains any display settings, it just defines a device tree node for the CLCD (PL11x) set as "disabled" and no panels are attached on any device tree. This I conclude that the hardware is dormant on existing systems, so we can without any problems switch the defconfig over from the old ARMCLCD frame buffer driver to the new PL11x DRM driver.
