This is fine, just mention it in commit msg.

These you need to consult with qcom-sata.txt. This could be a following
commit which will integrate qcom-sata.txt and remove it. Either you have
binding document for all devices or you create a common part, like for UFS:
https://lore.kernel.org/linux-devicetree/20220222145854.358646-1-krzysztof.kozlowski@xxxxxxxxxxxxx/
https://github.com/krzk/linux/commits/n/dt-bindings-ufs-v2

The choice depends more or less on complexity of bindings, IOW, how big
and complicated bindings would be if you combine everything to one YAML.

In the case of UFS, the devices differ - by clocks, resets, phys and
sometimes supplies. Therefore it easier to have one common shared part
and several device bindings.

AHCI looks more consistent - except that Qualcomm - so maybe better to
have one document.

This would need allOf+if.

Keeping reviewed-by would be fine when adding compatibles and bumping
maxItems, but in your case you need to rework these bindings. Either by
growing document with several "if:" or by splitting them, so it will be
significant change. Skip my review then.
