[PATCH 0/8] dmaengine: ti: Add support for BCDMA v2 and PKTDMA v2

[Sai Sree Kartheek Adivi]

This series adds support for the BCDMA_V2 and PKTDMA_V2 which is
introduced in AM62L.

The key differences between the existing DMA and DMA V2 are:
- Absence of TISCI: Instead of configuring via TISCI calls, direct
  register writes are required.
- Autopair: There is no longer a need for PSIL pair and instead AUTOPAIR
  bit needs to set in the RT_CTL register.
- Static channel mapping: Each channel is mapped to a single peripheral.
- Direct IRQs: There is no INT-A and interrupt lines from DMA are
  directly connected to GIC.
- Remote side configuration handled by DMA. So no need to write to PEER
  registers to START / STOP / PAUSE / TEARDOWN.
