"simple-panel" is the common compatible for all panels that the driver supports. If no compatible for a specific panel is given, the driver supports a generic panel with an ENABLE GPIO, an attached backlight and a regulator. This is what's being used here.=20 Lothar Wa=C3=9Fmann --=20 ___________________________________________________________ Ka-Ro electronics GmbH | Pascalstra=C3=9Fe 22 | D - 52076 Aachen Phone: +49 2408 1402-0 | Fax: +49 2408 1402-10 Gesch=C3=A4ftsf=C3=BChrer: Matthias Kaussen Handelsregistereintrag: Amtsgericht Aachen, HRB 4996 www.karo-electronics.de | info-AvR2QvxeiV7DiMYJYoSAnRvVK+yQ3ZXh@public.gmane.org ___________________________________________________________ -- To unsubscribe from this list: send the line "unsubscribe devicetree" i= n the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
