@JannesVolkens Are there real changes in driver implementation or just renamings? 

When I took a look to the register maps of both sensors, I figured out the following:

- the `ACCEL_CONFIG` register is splitted into two registers (register 28 an 29). The additional register `ACCEL_CONFIG2` only contains the settings `ACCEL_FCHOICE_B` and  `A_DLPF_CFG` that seem to be new in MPU9250.
- additional new configuration `FCHOICE_B` in `GYRO_CONFIG` register 26
- in MPU9250, the FIFO mode can be configured by by an additional bit in register 26.

Did you check in detail that all the bits in new registers are not required to be handled?
