[PATCH v10 02/10] drm/i915/psr: Add intel_psr_use_trans_push to query if TRANS_PUSH is used

Jouni Högander
2026-01-26T08:00:38Z

This is a preparation to start using trans push as a PSR "Frame Change"
event. It adds intel_psr_use_trans_push placeholder which return false for
now until we have everything in place.

v2:
- modify commit message
- add TODO
