[Intel-gfx] [PATCH 0/7] drm/i915: Add support for LTTPR non-transparent link training mode

[Imre Deak]

Add the drm-core helpers and register definitions required to detect
LTTPRs and perform the link training in non-transparent mode. In i915
switch to non-transparent link training mode if any LTTPR is detected.
