This is the only place where Truly is mentioned. The panel vendor is
either Truly or it is Himax, it can't be a mix. From this example and
your patch description it seems like Truly is the manufacturer of the
panel, hence the panel compatible should really be:
compatible = "truly,tft480800-16-e";
May I change the compatible string to be '"truly,tft480800-16-e-dsi"?
This way, the dsi driver may match the dsi device.
That it uses an HX8369A chip internally is really secondary, at least
regarding the binding. If we ever get need to support multiple panels
with the same driver IC the proper solution would be to abstract that
code out into a helper library that is used from the various panel
drivers.
