Then we can consider CPPI 4.1 DMA support. I guess I have misunderstood you. I though you asked to send this patch alone (separated from the series that adds CPPI 4.1 support to DA8xx). I still not sure to understand what you want me to do.

DA8xx driver is registering and using the CPPI DMA controller but actually, the DA8xx has a CPPI 4.1 DMA controller. Update the driver to register and use the CPPI 4.1 DMA controller.
