Subject: drm/i915: Add struct to hold IP version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: a5b7ef27da60c90bad5b2d41af3aa82da480a188
Patch-mainline: v5.17-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
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.
