In preparation for the async_tx (dmaengine client) API this patch:
1/ introduces struct dma_async_tx_descriptor as a common field for all
dmaengine software descriptors. The primary role of this structure
is to enable callbacks at transaction completion time, and support
transaction chain
This effectively makes channels a shared resource rather than tying them
to a specific client. dmaengine now assumes that clients will internally
track how many channels they need and dmaengine will learn if the client cares
about
a channel at dma_event_callback time. This also enables a client

The parity calculation for an expansion operation is the same as the
