From: Ritesh Kumar <[email protected]> Nord requires different TX voltage-swing and pre-emphasis levels for both eDP and DP modes. Add four pairs of 4x4 tables covering RBR/HBR and HBR2/HBR3 for each mode, sourced from HPG Tables 2-2, 2-4, 2-6-a and 2-6-b, and wrap them in qcom_edp_swing_pre_emph_cfg descriptors. The eDP RBR/HBR swing table reuses the existing edp_swing_hbr_rbr directly; all other tables are new.
