You are right. The SDHCI driver should work just fine without implementing pre_req and post_req but you wont see any performance increasing for DMA usage. In order to benefit from the patchset you need to implement pre_req and post_req. If you run into trouble implementing those hooks or if you have any questions please let me know. Regards, Per
