+
+description:
+ The PKTDMA V2 is intended to perform similar functions as the packet mode
+ channels of K3 UDMA-P. PKTDMA V2 only includes Split channels to service
+ PSI-L based peripherals.
+
+ The peripherals can be PSI-L native or legacy, non PSI-L native peripherals
+ with PDMAs. PDMA is tasked to act as a bridge between the PSI-L fabric and the
+ legacy peripheral.
