Quoting Matt Roper (2023-08-21 15:06:29-03:00)
>Many of the IS_METEORLAKE conditions throughout the driver are supposed
>to be checks for Xe_LPG and/or Xe_LPM+ IP, not for the MTL platform
>specifically. Update those checks to ensure that the code will still
>operate properly if/when these IP versions show up on future platforms.
>
>v2:
> - Update two more conditions (one for pg_enable, one for MTL HuC
> compatibility).
>v3:
> - Don't change GuC/HuC compatibility check, which sounds like it truly
> is specific to the MTL platform. (Gustavo)
> - Drop a non-lineage workaround number for the OA timestamp frequency
> workaround. (Gustavo)
