-Subject: [PATCH] MLK-22798-1: dmaengine: fsl-edma-v3: do not enable interrupt
- in dev_2_dev
-
-Do not enable interrupt in dev_2_dev with cyclic case, since in such
-case no any interrupt needed. Otherwise many interrupt will come in
-every 64 words transfered in ASRC case, which cause heavy system
-loading.
