Maxime, thanks for your comments. I'll update the patch, but meanwhile,
I have some remarks/questions, see below.

A20 SoC (found in Cubieboard 2 among others) requires different LVDS set
up procedure than A33. Timing controller (tcon) driver only implements
sun6i-style procedure, that doesn't work on A20 (sun7i).
The support for such procedure is ported from u-boot and follows u-boot
naming convention: SUN6I*
