Please can you put the .dts changes in a separate patch?

Also enabling it for a board should be in a separate patch.

And the actual driver should be in a driver patch. So I think you want
3 patches altogether.

What is the purpose of this? Could it instead be a table of values?
struct something {
u8 addr;
u8 bits;
u8 offset;
}
static const struct something some_table[] = {
{ 1, 2, 3},
...
};

Is this different from rk_clrsetreg() ? Can you put this next to that function?

There are two different things:
- Compiling in the driver
- Deciding which one to use
Here I think you have one config for both. I think the config should
just decide whether to compile in the driver. The device tree, or some
environment variable, should select which to use.

Is it possible to have more than one port? The above settings are in
the device tree, aren't they? For example on firefly I think it uses
HDMI if it can detect it.

I suppose you can pick the first panel, but can't you use the DT to
tell you which one?
See rk_lvds.c for what it does.

Can you use rk_mipi_probe() etc. for these functions just to make them
more unique?

Maybe we need a way to select which depth to use?

And it should probably calculate this, so HDMI continues to work.
