2019-06-21dtc: Add GPLv2 SPDX tags to files missing license textRob Herring1-0/+1
A couple of dtc files are missing licenses. Add GPL-2.0-or-later SPDX tag to them. Signed-off-by: Rob Herring <robh@kernel.org> Message-Id: <20190620211944.9378-7-robh@kernel.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2010-11-13dtc: Add code to make diffing trees easierDavid Gibson1-0/+38
This patch adds a "dtdiff" script to do a useful form diff of two device trees. This automatically converts the tree to dts form (if it's not already) and uses a new "-s" option in dtc to "sort" the tree. That is, it sorts the reserve entries, it sorts the properties within each node by name, and it sorts nodes by name within their parent. This gives a pretty sensible diff between the trees, which will ignore semantically null internal rearrangements (directly diffing the dts files can give a lot of noise due to the order changes).
