Subject: [PATCH v13 0/2] add uart DMA function
Date: Thu, 23 May 2019 15:35:07 +0800 [thread overview]
Message-ID: <1558596909-14084-1-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/mediatek.
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
Changes compared to v12
-rename parameters
-remove direction
Changes compared to v11
-modify TX/RX
-pause function by software
Changes compared to v10
-modify DMA tx status function
-modify 8250_mtk for DMA rx
-add notes to binding Document.
Changes compared to v9
-rename dt-bindings file
-remove direction from device_config
-simplified code
Changes compared to v8
-revise missing items
Changes compared to v7:
-modify apdma uart tx
Changes compared to v6:
-Correct spelling
Changes compared to v5:
-move 'requst irqs' to alloc channel
-remove tasklet.
Changes compared to v4:
-modify Kconfig depends on.
Changes compared to v3:
-fix CONFIG_PM, will cause build fail
Changes compared to v2:
-remove unimportant parameters
-instead of cookie, use APIs of virtual channel.
-use of_dma_xlate_by_chan_id.
Changes compared to v1:
-mian revised file, 8250_mtk_dma.c
--parameters renamed for standard
--remove atomic operation
