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