Hi, This series has been first proposed by Jernej Skrabec[1]. As this series is mandatory for SPDIF/I2S support and because he is busy on Cedrus stuff. I asked him to make the minor change requested and repost it. Authorship remains to him. I have tested this series with SPDIF driver and added a patch to enable DMA_SUN6I_CONFIG for arm64. Original Post: " DMA engine engine on H6 almost the same as on older SoCs. The biggest difference is that it has slightly rearranged bits in registers and it needs additional clock, probably due to iommu. These patches were tested with I2S connected to HDMI. I2S needs additional patches which will be sent later. Please take a look. Best regards, Jernej " Thanks, Clément Changes since v2: - Drop the change of "dma-request" default value Changes since v1: - Enable DMA_SUN6I in arm64 defconfig - Change mbus_clk to has_mbus_clk - Collect Rob H. reviewed-by Clément Péron (1): arm64: defconfig: enable Allwinner DMA drivers Jernej Skrabec (6): dt-bindings: arm64: allwinner: h6: Add binding for DMA controller dmaengine: sun6i: Add a quirk for additional mbus clock dmaengine: sun6i: Add a quirk for setting DRQ fields dmaengine: sun6i: Add a quirk for setting mode fields dmaengine: sun6i: Add support for H6 DMA arm64: dts: allwinner: h6: Add DMA node .../devicetree/bindings/dma/sun6i-dma.txt | 9 +- arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 12 ++ arch/arm64/configs/defconfig | 1 + drivers/dma/sun6i-dma.c | 147 +++++++++++++----- 4 files changed, 132 insertions(+), 37 deletions(-) -- 2.20.1
