[PATCH v2 52/53] dmaengine: sun6i: Declare slave capabilities for the generic code

From: Maxime Ripard
Date: Thu Oct 16 2014 - 06:23:48 EST


Now that the generic slave caps code can make use of the device assigned
capabilities, instead of relying on a callback to be implemented.

Make use of this code.
