"The "Open Firmware Device Tree", or simply Device Tree (DT), is a
data structure and language for describing hardware. More
specifically, it is a description of hardware that is readable by an
operating system so that the operating system doesn't need to hard
code details of the machine"

"What it does do is provide a language for decoupling the hardware
configuration from the board and device driver support in the Linux
kernel (or any other operating system for that matter)."

And like I said, we already had bindings for out of tree bindings,
like this one:
https://patchwork.kernel.org/patch/9275707/

Which triggered no discussion at the time (but the technical one,
hence a v2, that should always be done).

That patch was dropped, only DT changes remains now, and do not depend
of that missing patch anyway.

DRM is really not important here. We could implement a driver using
i2c as far as the DT is concerned.

FreeBSD for example uses a different, !DRM framework to support our
display stack, and still uses the DT.
