Subject: [v2 1/2] dmaengine: fsl-dpaa2-qdma: Add the DPDMAI(Data Path DMA Interface) support
The MC exports the DPDMAI object as an interface to operate the DPAA2 QDMA
Engine. The DPDMAI enables sending frame-based requests to QDMA and receiving
back confirmation response on transaction completion, utilizing the DPAA2 QBMan
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 objects.
3. Supports different scheduling options for processing received packets:
- Queues can be configured either in 'parked' mode (default), oattached
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.
