From 1cac81b4383d6be337fb9e17540c360311a3548f Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 17 Nov 2014 14:42:52 +0100 Subject: [PATCH] dmaengine: sun6i: Declare slave capabilities for the generic code 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.
