[PATCH v2 0/2] DW DMAC: update device tree

Show all headers | View raw

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.
