Ensure consistent sample rate with IIO

Hello all, I have been searching for a clear answer on how to ensure consistent sample rates from an ADC using IIO attached via SPI.  Given IRQ latency etc. is it even possible to ensure consistent sample rates with IIO?  If so what would be the typical approach for a sample rate of >= 128ksps?  FYI, if it's helpful we are currently using an IMX6UL and Linux 3.14.52.

 

Any advice, links and code (other than RTFM) would be greatly appreciated. 

 

Thanks.
