It is actually a lvds panel connected through a rga-lvds bridge. But I really have no idea about what does a port mean in fimd node.
Also how should I configure this panel size? I think the i2c found on the panel schematic, but it more likely to be used a touch screen touth. Also the touch screen is not supported in currently driver.
