Contributing to dtc or libfdt

There are two ways to submit changes for dtc or libfdt:

• Post patches directly to the the devicetree-compiler mailing list.
• Submit pull requests via Github

Adding a new function to libfdt.h

The shared library uses libfdt/version.lds to list the exported functions, so add your new function there. Check that your function works with pylibfdt. If it cannot be supported, put the declaration in libfdt.h behind #ifndef SWIG so that swig ignores it.

Tests

Test files are kept in the tests/ directory. Use make check to build and run all tests.

If you want to adjust a test file, be aware that tree_tree1.dts is compiled and checked against a binary tree from assembler macros in trees.S. So if you change that file you must change tree.S also.
