The module is connected to the main board I2C bus so I can detect its presence by checking if chips connected to the bus are detected. Using a GPIO would have been much easier, but that's life :-) > You could then configure the pins dynamically in your driver. That's what I'm doing. As dynamic pin configuration requires board-specific knowledge in the device driver I would have liked to avoid that if possible.
