[PATCH v2 0/2] DW DMAC: update device tree
From: Eugeniy Paltsev
Date: Fri Nov 18 2016 - 11:53:21 EST
It wasn't possible to enable some features like
memory-to-memory transfers or multi block transfers via DT.
It is fixed by these patches.
Changes for v2:
* I thought about is_memcpy DT property: all known devices, which
use DT for configuration, support memory-to-memory transfers.
So we don't need to read it from DT. So enable it by default,
if we read configuration from DT.
* Use "multi-block" instead of "hw-llp" name to be more clear.
* Move adding DT property and adding documentation for this
property to one patch.
