Linux/AM3358: Mapping interrupt from ADC with EDMA event

Part Number: AM3358

Tool/software: Linux

I'm writting a program that takes sample in non-stop manner on beaglebone.

If ADC's FIFO0 sends an interrupt to EDMA, how can I map that interrupt with a specific DMA event ?

And, Do I need to insert a device tree when the program run from pru ?. I'm a little confused about device tree.

One more question, If EDMA sends a interrupt to MPU, how can I map it with ISR.

Thanks in advance!
