 *      @brief      An I2C-based driver for Invensense gyroscopes.
 *      @details    This driver currently works for the following devices:
 *                  MPU6050
 *                  MPU6500
 *                  MPU9150 (or MPU6050 w/ AK8975 on the auxiliary bus)
 *                  MPU9250 (or MPU6500 w/ AK8963 on the auxiliary bus)
