Subject: [PATCH v3 0/5] dmaengine: Add support for AM62A SoC DMAs

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.

v3:
Fix yaml bindings to constraint regs and reg-names per compatible

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