To differentiate\nbetween the different generations, the patch adds an enum value to the OF config\ndata.\n\nThe A83t uses the same register layout as the A23, so this series also fixes the missing\nclock gating setting for the A83t.\n\nThe A64 is register compatible to the H3, but supports less channels and has a different\nset of endpoints. Add a new compatible string to the device tree and the driver.\n\nStefan Brüns (3):\n dmaengine: sun6i: Correct DMA support on H3\n arm64: allwinner: a64: Add device node for DMA controller\n dmaengine: sun6i: Add support for Allwinner A64\n\n .../devicetree/bindings/dma/sun6i-dma.txt | 1 +\n arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 13 ++\n drivers/dma/sun6i-dma.c | 135 +++++++++++++++------\n 3 files changed, 109 insertions(+), 40 deletions(-)" }
