Because the sampling edge of the panel can be different (is there even such an edge for LVDS panel?). What we care about specifying here is the edge on which the FIN3385 samples the data on the Parallel bus, and that is a property of the FIN3385, because that is configured via a dedicated pin on the FIN3385. > The property tell when data are sampled and the FIN3385 Parallel-to-LVDS > is the one that transmit the data - not then one that samples the data. > Correct? Not correct I'm afraid, see above. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
