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

57 PSI-L thread ID of the remote (to BCDMA) end.
58 Valid ranges for thread ID depends on the data movement direction:
59 for source thread IDs (rx): 0 - 0x7fff
60 for destination thread IDs (tx): 0x8000 - 0xffff
62 Please refer to the device documentation for the PSI-L thread map and
63 also the PSI-L peripheral chapter for the correct thread ID.
