[PATCH v2 2/3] dmaengine: fsl-dpaa2-qdma: Upgrade DPDMAI functions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch:
1. Reworks DPDMAI interface functions.
2. Update DPDMAI interfaces to support MC firmware V10.8.0 and above.
   From MC firmware V10.8.0, each DPDMAI supports 8/16 transaction
   queues according to the number of CPUs instead of max 2 queues
   before.

Signed-off-by: Guanhua Gao <guanhua.gao@xxxxxxx>
---
 - Update qdma callback function according to the change of transaction
   queues.
 - Clarify the description of patch.
 - Update copyright year.
