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*
changes too, right?
Hm, I agree. I think it would be reasonable to include LVDS0/1 pins and
sample (but disabled) lvds panel, connected to tcon to
arch/arm/boot/dts/sun7i-a20.dtsi. Does that make sense to you? Would you
expect dts changes in the same patch or separate?
P.S. This is my first patch

I jave just submitted version 2 of the patches - set of 2 patches this
time. Addressed your comment

Define pins for LVDS channels 0 and 1, configure reset line for tcon0 and
provide sample LVDS panel, connected to tcon0.

Different sunxi flavors require slightly different sequence for enabling
LVDS output. This allows to differentiate between them.

Hopefully that wasn't too much complaining for you :) If you have any
insight on possible causes or attack vectors on any of these, that would
help a lot. Also, please feel free

Can you give me an idea how that compatible might look like?
tcon0: lcd-controller@1c0c000 {
compatible = "allwinner,sun7i-a20-tcon",
"allwinner,lvds";
or
tcon0: lcd-controller@1c0c000 {
compatible = &quo

Subject: [PATCH] Mark tcon0 to be the only tcon capable of LVDS on sun7i
Address all outstanding review comments.
Maxime, please confirm I've got "document the new
compatibles" part right.

Timing controllers on A20 are not equivalent: tcon0 on A20 supports
LVDS output and tcon1 does not. Separate the capabilities by
introducing independent set of quirks for each of the tcons.

What is the status of this patch? Was this committed to any branch? Is
it pending for merge to the mainline? Do I have to do anything in order

Since Linus' merge window is now open, do I have to do anything to get
this merged into the mainline kernel?
