G'Day,
I am writing a driver for a 1-wire interface device, and was a little stuck on the major number for register_chrdev(). I checked Documentation/devices.txt, but there does not yet seem to be anything assigned (no surprise, really). I understand I can pick an unassigned numer, but that could become a pain in future, so if possible I would like to stick with an existing device. My question is simply this: does anyone know whether or not there is an existing device similar enough to 1-wire that I could use it? Perhaps that line of thinking is barking up the wrong tree, but it makes sense to me at least
