Hi,

These three patches fix the "i915 DDI PHY state mismatch" errors
in display runtime power management paths. The patches are cherry-picked
from the upstream kernel. The patches are for bxt-rebase brach and tested
on Joule.

95a7a2a drm/i915/bxt: Set DDI PHY lane latency optimization during modeset
67856d4 drm/i915/bxt: Use PHY0 GRC value for HW state verification
d4d6279 drm/i915: Set crtc_state->lane_count for HDMI
