-     - Called with a command and an argument
-       + The command is one of the values listed by the enum

-         in the DMA_SLAVE_CONFIG.
-
-  * device_slave_caps
-    - Called through the framework by client drivers in order to have
-      an idea of what are the properties of the channel allocated to
-      them.
-    - Such properties are the buswidth, available directions, etc.
-    - Required for every generic layer doing DMA transfers, such as
-      ASoC.

+     - This call is mandatory for slave operations only. This should NOT be
+       set or expected to be set for memcpy operations.
+       If a driver support both, it should use this call for slave
+       operations only and not for memcpy ones.
+
