H3, but missed\nsome differences between the original A31 and A83T/H3.\n\nThe first patch add a variable to group different SoC generations, i.e. A31,\nA23+A83T, H3+later, and uses it to for the correct clock autogating setting.\n\nThe second and fourth patches reuse this variable to reflect changes in the\nchannel config register, i.e. different field offsets, new burst widths/lengths.\n\nThe third patch restructures some code required for the fourth patch.\n\nPatch 5 restructures the code to decouple some controller details (e.g. channel\ncount) from the compatible string/the config.\n\nPatches 6, 7 and 8 introduce and use the \"dma-chans\" property for the A64. Although\nregister compatible to the H3, the channel count differs and thus it requires a\nnew compatible. To avoid introduction of new compatibles for each minor variation,\nanything but the register model is moved to devicetree properties. There\nis at least one SoC (R40) which can then reuse the A64 compatible, the same\nwould have worked for A83T+V3s.\n\nPatches 9 and 10 add the DMA controller node to the devicetree and add the DMA\ncontroller reference to the SPI nodes.\n\nThis patch series could be called v2, but the patches were split and significantly\nrestructured, thus listing changes individually is not to meaningful.\n\nStefan Brüns (10):\n dmaengine: sun6i: Correct setting of clock autogating register for\n A83T/H3\n dmaengine: sun6i: Correct burst length field offsets for H3\n dmaengine: sun6i: Restructure code to allow extension for new SoCs\n dmaengine: sun6i: Enable additional burst lengths/widths on H3\n dmaengine: sun6i: Move number of pchans/vchans/request to device\n struct\n arm64: allwinner: a64: Add devicetree binding for DMA controller\n dmaengine: sun6i: Retrieve channel count/max request from devicetree\n dmaengine: sun6i: Add support for Allwinner A64 and compatibles\n arm64: allwinner: a64: Add device node for DMA controller\n arm64: allwinner: a64: add dma controller references to spi nodes\n\n .../devicetree/bindings/dma/sun6i-dma.txt | 26 +++\n arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 15 ++\n drivers/dma/sun6i-dma.c | 207 ++++++++++++++++-----\n 3 files changed, 197 insertions(+), 51 deletions(-)" }
