[Intel-gfx] [PATCH 1/3] drm/i915: Add struct to hold IP version
José Roberto de Souza

Wed Oct 20 00:23:51 UTC 2021
Adding a structure to standardize access to IP versioning as future
platforms will have this information populated at runtime.
The constant platform display version is not using this new struct but
the runtime variant will definitely use it.
