Subject: [PATCH v2 0/4] add uart DMA function
Date: Wed, 5 Dec 2018 16:42:56 +0800 [thread overview]
Message-ID: <1543999380-7946-1-git-send-email-long.cheng@mediatek.com> (raw)
In Mediatek SOCs, the uart can support DMA function.
Base on DMA engine formwork, we add the DMA code to support uart. And put the code under drivers/dma.
This series contains document bindings, Kconfig to control the function enable or not,
device tree including interrupt and dma device node, the code of UART DM
Changes compared to v1:
-mian revised file, 8250_mtk_dma.c
--parameters renamed for standard
--remove atomic operation
Long Cheng (4):
dt-bindings: dma: uart: add uart dma bindings
dmaengine: mtk_uart_dma: add Mediatek uart DMA support
serial: 8250-mtk: add uart DMA support
arm: dts: mt2701: add uart APDMA to device tree
