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 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.
