Hi,
The commit: d9dbb97be0e4a550457aec5f11afefb446169c90 "mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end of dw mmc transfer.
For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) - and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB) the default timeout is to short.
The new value - 20 seconds - takes into account the situation when SD card triggers internal clean up. Such process may take more than 10 seconds on some cards.

Are there any more questions regarding this patch or is it ready for submission as fix for v2015.10?
