Hi If you want I work with a Allwinner A20 (my board are derived from OlinuXino-Micro-A20), and I will interest with LVDS function.
I use your patch but I have nothing to display on my screen. You can see my work on https://github.com/Philippe12/linux-sunxi/tree/sun7i-A20-lvds My hardware is good, it word with u-boot and a older kernel 3.4.104 I use a dlc screen (dlc0700DDG-T-11) my fault is probably on simple-panel information but I didn't seen were If you can tell me some things to check.
