Hi Jonathan, this is required for further patches coming soon. I am planning to add support for full 9-axis on MPU9250, using the chip i2c master to drive the integrated magnetometer and retrieve all data in the MPU FIFO. It will be behind a kernel config option to not break existing support driving the magnetometer from the kernel. Hope to have this cleaned-up and ready soon.
