/* Starting with Haswell, different DDI ports can work in FDI mode for * connection to the PCH-located connectors. For this, it is necessary to train * both the DDI port and PCH receiver for the desired DDI buffer settings. * * The recommended port to work in FDI mode is DDI E, which we use here. Also, * please note that when FDI mode is active on DDI E, it shares 2 lines with * DDI A (which is used for eDP) */
