[PATCH 0/2] drm/i915/dsi: Fix error on DSI video mode command

In CI system, the Broxton with DSI display throws an error message with

*ERROR* Video mode command 0x00000041 send failed.

In order to get rid of the error message, we should send SHUTDOWN before
MIPI_SEQ_DISPLAY_OFF for VBT's higher than v3.

While at here, let's add a check if we try to send the same MIPI command
consecutively.

Mika Kahola (2):
  drm/i915/dsi: Send SHUTDOWN only for v3+ VBT's
  drm/i915/dsi: Return early if MIPI control unchanged
