Commit Message

Vaishnav Achath Oct. 10, 2023, 11:17 a.m. UTC 
  J784S4 has a dedicated BCDMA controller for the Camera Serial Interface.
Events from the BCDMA controller instance are routed through the
main UDMA interrupt aggregator as unmapped events. Add the node for
the DMA controller and keep it disabled by default.

See J784S4 Technical Reference Manual (SPRUJ52)
for further details: http://www.ti.com/lit/zip/spruj52

V1->V2:
    * Fix indentation for the reg entries.
