     10 * SOF ABI versioning is based on Semantic Versioning where we have a given
     11 * MAJOR.MINOR.PATCH version number. See https://semver.org/
     12 *
     13 * Rules for incrementing or changing version :-
     14 *
     15 * 1) Increment MAJOR version if you make incompatible API changes. MINOR and
     16 *    PATCH should be reset to 0.
     17 *
     18 * 2) Increment MINOR version if you add backwards compatible features or
     19 *    changes. PATCH should be reset to 0.
     20 *
     21 * 3) Increment PATCH version if you add backwards compatible bug fixes.
