This is not question about a dozen drivers, to be clear.

I just want to break out the drivers that have an identifiable
display controller that differs from the others, especially this one.

The rest of the drivers inside of this boe driver I can't really tell,
they seem related? We don't know?

So the Ilitek ILI9882t is an obvious break-out.

For the rest, I guess I would be happier if the Chromium people
could use their leverage with vendors to muscle out the details
about display controller vendors and provide #defines for all
magic commands, we all dislike these opaque firmware-looking
jam tables.

Cong already stated that he indeed has the datasheet for the
ILI9882t controller at hand, had I come in earlier I would have
asked for all of those sequences to be provided with proper
#defines instead of 0xff 0x98 0x82 0x01... but I'm late to the
show.
