oh, sure. Will add this:

    The i.MX SDMA engine can read from / write to multiple successive
    hardware FIFO registers, referred to as "Multi FIFO support". This is
    needed for the micfil driver and certain configurations of the SAI
    driver. This patch adds support for this feature.
    
    The number of FIFOs to read from / write to must be communicated from
    the client driver to the SDMA engine. For this the struct
    dma_slave_config::peripheral_config field is used.

Sascha
