+description: |
+  The BCDMA V2 is intended to perform similar functions as the TR mode channels
+  of K3 UDMA-P. BCDMA V2 includes block copy channels and Split channels.
+
+  Block copy channels mainly used for memory to memory transfers, but with
+  optional triggers a block copy channel can service peripherals by accessing
+  directly to memory mapped registers or area.
+
+  Split channels can be used 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.
