The hw module is quite similar but register positions and channels available are different. So, seems a good chance to add a mcf-edma.c driver, starting/looking from fsl-edma.c. What do you think ? Is there anything already done about, maybe ? In case i would like to try to write an initial version of this driver. And Merry Christmas time to all. Regards, Angelo Dureghello
