[PATCH 0/7] Use trans push mechanism to generate frame change event

[Jouni Högander]

Currently we are using "automatic" frame change event generation. The
event is generated by any access to plane or pipe registers.

We have option to use "PSR PR Frame Change Enable" bit in TRANS_PUSH
register to enable frame change event generation on trans push. When
this bit is set "automatic" frame change event generation doesn't work
anymore.

This patch set is taking trans push mechanism into use.

Jouni Högander (7):
  drm/i915/psr: Add TRANS_PUSH register bit definition for PSR
  drm/i915/vrr: Do not overwrite TRANS_PUSH PSR Frame Change Enable
  drm/i915/vrr: Use TRANS_PUSH mechanism for PSR frame change
  drm/i915/psr: Rename psr_force_hw_tracking_exit as psr_force_exit
  drm/i915/psr: Simplify frontbuffer invalidate/flush callbacks
  drm/i915/psr: Add VRR send push interface for PSR usage
  drm/i915/display: Generate PSR frame change event on cursor update
