xpadneo uses file-level licensing via SPDX identifiers.
- Kernel driver code (files linked into the kernel module, especially
hid-xpadneo/src/**) is licensed under GPL-2.0-only. - Non-driver content (for example documentation, examples, tooling, and helper scripts) is generally licensed under GPL-3.0-or-later, unless a file states otherwise.
By submitting a contribution, you agree that your changes are licensed under the license specified by the SPDX header in each file you modify.
If you add a new file, you must add an SPDX license identifier at the top of that file and choose the license appropriate for its scope.
