Octeon supports up to 16 GPIO pins and interrupts. I'd suspect there are other things connected up with GPIO on-board than GPIO pins exposed to the outside world, but even if that's not the case, that's still the number of GPIO pins the SoC supports. It's possible that the EdgeRouter Lite uses a different pin for its F/D button. According to the driver, gonzo used the CAM-0100's pin assignment as the default. It should be easy to extract a list of pin assignments we care about from looking at the patches from Ubiquiti to the Simple Executive and Linux, but I haven't looked personally. (I don't ever use GPIO on Octeon.) The octeon_gpio_pins array probably needs to be configured at boot based on board type. (So it should normally be 16 items (or 16 plus a terminator) and get filled out by board type, I'd say.) Thanks, Juli.
