Subject: dmaengine: fsl-edma: dmatest timeout

Hi

When I executed the following command to do dmatest on the imx8qm platform,

I found that the timeout occurred on the current mainline kernel:

modprobe dmatest run=1 iterations=42

I found that the completion interrupt was not received in 
fsl_edma3_tx_handler().

I didn't find any special configuration from the manual. Can anyone give 
some suggestions?

thanks
