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";

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.
