Subject: [PATCH 0/4] add uart DMA function
Date: Thu, 20 Sep 2018 14:41:09 +0800 [thread overview]
Message-ID: <1537425673-18807-1-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 DMA function.
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
