Have a look at the GPIO_BT8XX driver to see how to do. Beware that GPIO_BT8XX is thought to drive physically altered boards (hence not working as brand new product - read the help message of the driver) while the bttv one has to keep all the other functionalities, so you may have less GPIO to play with because some are wired to something on the board itself. cheers, Domenico -- 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
