The figure 1-3 on page 6 shows both Disp-1 and Disp-2 going to the DVI-I connector, however the output of Disp-2 goes through the DAC so I suppose that's for the VGA pins. The figure 9-1 seems to be in conflict with that. DISP1_DAT isn't used at all there, but DISP2_DAT (albeit different pin ranges) go to both the ADV7123 and TFP410PA. > It might also be useful to find out which GPIOs are connected to the > TFP410 power down and reset lines. Yes, indeed. Luckily it works in u-boot so that's a reference.
