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 Long Cheng (2): arm: dts: mt2712: add uart APDMA to device tree serial: 8250-mtk: modify uart DMA rx arch/arm64/boot/dts/mediatek/mt2712e.dtsi | 51 +++++++++++++++++++++++++++++ drivers/tty/serial/8250/8250_mtk.c | 49 +++++++++++---------------- 2 files changed, 71 insertions(+), 29 deletions(-) -- 1.7.9.5 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
