| Subject: [PATCH] dmaengine: fsl-dpaa2-qdma: Add the DPDMAI(Data Path DMA
 | |
|  Interface) support
 | |
| 
 | |
| The MC(Management Complex) exports the DPDMAI(Data Path DMA Interface)
 | |
| object as an interface to operate the DPAA2(Data Path Acceleration
 | |
| Architecture 2) qDMA Engine. The DPDMAI enables sending frame-based
 | |
| requests to qDMA and receiving back confirmation response on transaction
 | |
| completion, utilizing the DPAA2 QBMan(Queue Manager and Buffer Manager
 | |
| hardware) infrastructure. DPDMAI object provides up to two priorities for
 | |
| processing qDMA requests.
 | |
| The following list summarizes the DPDMAI main features and capabilities:
 | |
| 	1. Supports up to two scheduling priorities for processing
 | |
| 	service requests.
 | |
| 	- Each DPDMAI transmit queue is mapped to one of two service
 | |
| 	priorities, allowing further prioritization in hardware between
 | |
| 	requests from different DPDMAI objects.
 | |
| 	2. Supports up to two receive queues for incoming transaction
 | |
| 	completion confirmations.
 | |
| 	- Each DPDMAI receive queue is mapped to one of two receive
 | |
| 	priorities, allowing further prioritization between other
 | |
| 	interfaces when associating the DPDMAI receive queues to DPIO
 | |
| 	or DPCON(Data Path Concentrator) objects.
 | |
| 	3. Supports different scheduling options for processing received
 | |
| 	packets:
 | |
| 	- Queues can be configured either in 'parked' mode (default),
 | |
| 	or attached to a DPIO object, or attached to DPCON object.
 | |
| 	4. Allows interaction with one or more DPIO objects for
 | |
| 	dequeueing/enqueueing frame descriptors(FD) and for
 | |
| 	acquiring/releasing buffers.
 | |
| 	5. Supports enable, disable, and reset operations.
 | |
| 
 | |
| Add dpdmai to support some platforms with dpaa2 qdma engine.
