As I understand, the 480 + 10 + 2 + 33 timing should be correct for both panels. > As for the touch panel on the ETM0700G0DH6, do you happen to know how > that's usually connected?

The ETM0700G0DH6 has a capacitive touch screen with an EDT-FT5406 controller connected via I2C, at least on the panels that I have seen. regards Philipp -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
