25      GPIO connected to the SDA line to hold low in order to wake up the
26      device.  In normal operation, the GPIO is set as input and will
27      not interfere in I2C communication.  There is no need for a GPIO
28      driving the SCL line.  If no GPIO is given, power management is disabled.
