Currently fastset is not supported, if mbus join state changes,
so whenever we have to switch mbus state, we have to force a full
modeset. This patch series makes fastset possible from MBUS state
point of view.

Stanislav Lisovskiy (4):
  drm/i915: Update mbus in intel_dbuf_mbus_update and do it properly
  drm/i915: Use old mbus_join value when increasing CDCLK
  drm/i915: Loop over all active pipes in intel_mbus_dbox_update
  drm/i915: Implement vblank synchronized MBUS join changes
