Subject: [PATCH v3 0/5] arm: aspeed: Add UART DMA support
Date: Mon, 20 Mar 2023 16:11:28 +0800 [thread overview]
Message-ID: <20230320081133.23655-1-chiawei_wang@aspeedtech.com> (raw)
This patch serias adds the 8250 driver with DMA support for AST26xx UART devices
v3 change:
- add error check against dma_to_phys
- revise UDMA binding
- remove UDMA binding header
- remove redundant header inclusions of UDMA driver
- fix incorrect UDMA channel number (14->28)
- place UDMA kconfig in alphabetical order
- collect Acked-by tags
v2 change:
- re-write UDMA driver based on the DMAEngine framework
- re-write 8250_aspeed driver with DMA support based on the 8250_dma implementation
- remove virtual UART part as there is already a 8250_aspeed_vuart driver
