I am really confused about how to connect an LVDS monitor to the board.
We used 3.x legacy kernel and used a .fex file for this in the past.
But it is time to move to mainline, and it is confusing me.
Since LVDS is not plug and play, we need to tell the parameters of the screen somehow. That is clear.
I found several ways of pushing parameters to the system:
1. Compile into kernel
2. Compile into U-boot
3. Device Tree
4. Device Tree Overlay
5. Kernel command line
According to these articles i have to compile them into U-boot:

http://linux-sunxi.org/LCD
But it seems to me that it is a step backwards compared to .fex files.
(and I have not figured out how to recompile U-boot in armbian yet)
I found a commit, which states that there is some support for LVDS on A20s:
https://github.com/torvalds/linux/commit/564c4815074291c40a584b1b05da3732beac990c#diff-ea438ea3ad237808b1c56c9c6ca647fe
This suggest that i could somehow use Device Tree.
Which i guess would be more future proof, but i do not know how to tell the exact parameters of the screen.
Also i need to set the brightness, and turn off the monitor sometimes, how do I do that nowadays?
