Changes for v2:
- patch splitted into 4
- add mcf-edma as minimal different parts from fsl-edma

Changes for v3:
none

Changes for v4:
- patch simplified from 4/4 into 2/2
- collecting all the mcf-edma-related changes

Changes for v5:
none

Changes for v6:
- adjusted comment header
- fixed bit shift with BIT()
- we need to free the interrupts at remove(), so removed all devm_
  interrupt related calls

Changes for v7:
none

Changes for v8:
- patch rewritten from scratch, splitted into 3, common code isolated,
  minimal changes from the original Freescale code have been done.
  The patch has been tested with both Iris + Colibri Vybrid VF50 and
  stmark2/mcf54415 Coldfire boards.

You moved code from fsl-edma.c which is licensed on GPL-2.0+. I think
that's not allowed as you effectively relicense the work on new
license.
