Hi Simon,
I have added your patch sources manually into the "Prepare v2012.04-rc1
release", because I got errors at apply. 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.
Greetings
Christian
Changes:
- Add device tree source file for Harmony board
- Add bug fix in display.c
- Patch based on the "Prepare v2012.04-rc1" release
