[PATCH v2 1/2] dt-bindings: dma: snps,dw-axi-dmac: Add JH8100 support

[Tan Chun Hau]

Add support for StarFive JH8100 SoC in Sysnopsys Designware AXI DMA
controller.

Both JH8100 and JH7110 require reset operation in device probe.
However, JH8100 doesn't need to apply different configuration on
CH_CFG registers.

This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed.

Best regards,
Krzysztof

Hi Krzysztof, thank you very much for the feedback,
Sorry I overlooked it.
Do you prefer I resend V2 patch or send a V3 patch to include the Acked-by ?
Thank you.

I resent the tag, you do not need to do anything.

Thanks,
