Also I added a device tree source file for Harmony. I tested the device tree source file for Harmony and your patch sources on our Harmony hardware and generated a new patch file: http://poeggi.dotsec.net/nvidia/uboot-lvds-init-patch/0001-Add-display-driver-and-LCD-support-for-Harmony-board.patch I hope it's all okay, this my first patch release. In the display.c source file I implemented a bug fix, because I get garbled images on the LCD without this fix.
