Currently the driver can be used with sDMA only due to the fact that the
sDMA bindings are using "real DMA_REQ + 1" indexing of the DMA requests.
This is not a case with the eDMA for example so the driver in current form
can not handle the case when it is used with eDMA.
Be precise with the compatible.
