Is this panel not based on newvision,nv3051d? If > not, then it probably should be a different binding. Lot's of panel > bindings have similar properties. It appears to be the same panel (or extremely similar, honestly I don't know because there are no external markings on it). However, this specific implementation seems to require MIPI_DSI_CLOCK_NON_CONTINUOUS, not using it prevents the panel from working. As for the existing panel MIPI_DSI_CLOCK_NON_CONTINUOUS stops it from working. The different binding essentially determines whether or not that flag is present, but otherwise everything else is identical. Chris > > Rob
