15 The Block Copy DMA (BCDMA) is intended to perform similar functions as the TR
16 mode channels of K3 UDMA-P.
23 Split channels can be used to service PSI-L based peripherals.
24 The peripherals can be PSI-L native or legacy, non PSI-L native peripherals
25 with PDMAs. PDMA is tasked to act as a bridge between the PSI-L fabric and the
