This series introduces support for various DMAs on TI's AM62A SoC under
K3 family of devices.

Apart from usual BCDMA and PKTDMA thats present on K3 family, AM62A has
a dedicated BCDMA for camera (CSI) with only RX DMA Channels.

Patch 1 adds bindings for this new DMA instance
Patch 2 fixes a bug that gets exposed due to RX only DMA
Patch 3 and 4 add base support for AM62A DMA
Patch 5 does BCDMA CSI RX specific enhancements.

v2:
Fix k3-bcdma.yaml as per Krzysztof 's comments
Address's Peter's comment on 2/5
