iio: imu: inv_mpu6050: new timestamp mechanism Check validity of interrupt timestamps by computing time between 2 interrupts. If it matches the chip frequency modulo 4%, it is used as the data timestamp and also for estimating the chip frequency measured from the system. Otherwise timestamp is computed using the estimated chip frequency. Signed-off-by: Jean-Baptiste Maneyrol <jmaneyrol@invensense.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
