From 6f3125ceb66120796f62e7797a1a313418a5911a Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Wed, 8 Mar 2017 10:13:09 +0100 Subject: [PATCH] dmaengine: imx-sdma: advertise correct residue granularity The SDMA hardware/driver does not actually report the transfer residue at burst size granularity, but in fact is only able to report residue after each finished segment.
