I'm not sure I understand what the question was. Is this about
whether we should remove the "slave_id" field in the slave
configuration?

Those sort of duplicate the request line information that comes
from the platform in a data structure that should be filled by
the device driver without platform specific knowledge.

I believe that is currently used by shmobile, and we won't be able
to kill that before that platform has been converted to use
dma_request_slave_channel.
