Yes. There have been plans for a long time...

Maybe it is now good enough. I'll take a look into it.

The problem is that they don't want to see any "private" bindings...

So we may have to edit things until it can be upstreamed.

And this sometimes leads to awkwards hacks and split up of things
that belong together, to finally get a feature complete devices tree
source like we currently have.

And there are long running plans to upstream some patches to gta04a3/4
device trees as well.
