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 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 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
