It's not really a mirror nor a fork, I guess it is something in
between.

It's a rewritten tree which extracts the DTS bits only from the kernel
source into a standalone source repo. It's produced using "git filter-
branch", all the scripting to do so is at:

https://git.kernel.org/pub/scm/linux/kernel/git/devicetree/devicetree-rebasing.git/tree/scripts

The conversion state is part of
https://github.com/ijc/devicetree-conversion-state-v3/, that repo
contains all of upstream Linux commits too, since the branches there
track the most recently converted inputs to support incremental
updates.

There's also the filter-map branch which maintains the state needed to
not have to redo the conversion every time (which from scratch took
days last time...)
