Hi, I'm trying to understand how to control GPIOs on a bt878 card, as described in this earlier post: http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/39342 I came across the file bttv-gpio.c in drivers/media/video/bt8xx, and the starting comment seems what I'm looking for: "sysfs-based sub driver interface for bttv mainly intented for gpio access" But I cannot understand how to enable this sysfs based access. Is there a kernel configuration somewhere? Where the gpios are supposed to show up in /sys? Thank you in advance for your help and excuse me if my question is trivial. -- Augusto Destrero, PhD -- 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
