Revision a1cf09031e641d3cceaca4a4dd20ef6a785bc9b3 authored by Maxime Ripard on 15 September 2015, 13:36:00 UTC, committed by Vinod Koul on 01 October 2015, 01:59:40 UTC
The addressing mode we were using was not only incrementing the address at
each microblock, but also at each data boundary, which was severely slowing
the transfer, without any benefit since we were not using the data stride.
Switch to the micro block increment only in order to get back to an
acceptable performance level.
