The commands are of necessity 16-bits. Using 16-bit words means this driver won't run on as many systems; folk will still need to use the ads7846 driver with tsc2046 chips.. and does not include > temerature > >> or voltage sensing capabilities.

Something the ads7846 driver could benefit from too ... again, two drivers is counterproductive. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
