...ode was updated to make it compatible with the current state of the driver. Here is how it now works. If the connection is DCB_OUTPUT_DP, call nouveau_dp_dpms() which does DP_SET_POWER and, if we are resuming, initiates DP link training by sending NV94_DISP_SOR_DP_TRAIN to have nv50_sor_mthd() call nouveau_dp_train().
