This patch series adds support for the Andes ATCDMAC300 DMA controller,
a memory-to-memory and peripheral DMA controller that provides
scatter-gather, cyclic, and slave transfer capabilities.

The ATCDMAC300 IP is embedded in AndesCore-based platforms or SoCs
such as AE350 and Qilai.

Changes in v4:
  - Use items list format with descriptions for reg property in DT binding
    as suggested by Conor Dooley
  - Re-add Acked-by from Conor Dooley for DT binding patch

Changes in v3:
  - Rename DT binding file from andestech,qilai-dma.yaml to
    andestech,ae350-dma.yaml
  - Deprecate IP-core-based compatible and align with SoC/platform-based
    compatible strings
  - Dropped Acked-by from Conor Dooley due to the above binding change
  - Remove "andestech,atcdmac300" from of_device_id table
  - Replace deprecated tasklet with threaded IRQ using
    devm_request_threaded_irq() and IRQF_ONESHOT
  - Update locking from spin_lock_bh() to spin_lock_irqsave()
  - Use builtin_platform_driver() instead of module_platform_driver()
  - Remove "select DMATEST" from Kconfig
  - Add separate MAINTAINERS patch (patch 3/3)

Please kindly review.
