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.
First of all, please, give time to reviewers to comment the patches. Usually it should be at least 24h (for the series that has been sent first time 1 week approximately).
Changes for v3: * Update existing platform data. We don't need to update existing DTS because default logic wasn't change: we don't set "is_nollp" if we read configuration from DT before. And we don't set it now if "multi-block" property doesn't exist in DTS.
See my comments in the patches. And do not send the updated version earlier than Monday, please.
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.
