Antti, for your records here's the I2C reply when the si2168 asks for the chip id from one of these newer D40 chips: 80 00 44 34 30 02 00 00 00 00 00 00 00 00 It might make sense to change the "unknown chip version Si21%d-%c%c%c" default message to include a hex dump of the first 5 bytes, to accelerate/aid future debugging issues. - Steve -- Steven Toth - Kernel Labs http://www.kernellabs.com -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
