      dmaengine: fsl-dpaa2-qdma: Add NXP dpaa2 qDMA controller driver for Layerscape SoCs · 7fdf9b05
      Peng Ma authored
      DPPA2(Data Path Acceleration Architecture 2) qDMA supports
      virtualized channel by allowing DMA jobs to be enqueued into
      different work queues. Core can initiate a DMA transaction by
      preparing a frame descriptor(FD) for each DMA job and enqueuing
      this job through a hardware portal. DPAA2 components can also
      prepare a FD and enqueue a DMA job through a hardware portal.
      The qDMA prefetches DMA jobs through DPAA2 hardware portal. It
      then schedules and dispatches to internal DMA hardware engines,
      which generate read and write requests. Both qDMA source data and
      destination data can be either contiguous or non-contiguous using
      one or more scatter/gather tables.
      The qDMA supports global bandwidth flow control where all DMA
      transactions are stalled if the bandwidth threshold has been reached.
      Also supported are transaction based read throttling.
      
      Add NXP dppa2 qDMA to support some of Layerscape SoCs.
      such as: LS1088A, LS208xA, LX2, etc.

      dmaengine: fsl-dpaa2-qdma: Add the DPDMAI(Data Path DMA Interface) support · f2835adf
      Peng Ma authored
      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.
