[Intel-xe] [PATCH v2 0/2] Remove GuC Reset in D3Hot path

[Riana Tauro]

During Runtime suspend/resume, GuC is reloaded for both
D3hot/D3Cold -> D0 transistions. It is not necessary for GuC to be
loaded everytime for D3hot->D0, only enable/disable ctb communication.

Rev2: Fix review comments

Riana Tauro (2):
  drm/xe: Add helper functions to toggle CT communication
  drm/xe: Toggle GuC CT communication for D3Hot Transition
