[Intel-gfx] [PATCH v4 01/11] drm/i915: Move display and media IP version to runtime info
Radhakrishna Sripada

Fri Sep 2 06:03:32 UTC 2022
Future platforms can read the IP version from a register and the
IP version numbers need not be hard coded in device info. Move the
ip version for media and display to runtime info.
On platforms where hard coding of IP version is required, update
the IP version in __runtime under device_info.
v2:
- Avoid name collision for ip versions(Jani)
