[PATCH v4 14/18] dt-bindings: PCI: qcom: Add "mhi" register region to supported SoCs
Posted by Manivannan Sadhasivam 2 years, 11 months ago
"mhi" register region contains the MHI registers that could be used by
the PCIe controller drivers to get debug information like PCIe link
transition counts on newer SoCs.

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. However, there's no need to repost patches *only* to add the
tags. The upstream maintainer will do that for acks received on the
version they apply.

https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540

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


Best regards,
Krzysztof
