I don't know the base here, but it's really, really different and it suggests you should add mt8188 to an enum with mt8173. Best regards, Krzysztof
Hi Krzysztof, Thanks for the reminder, because MT8188 is not related to MT8173, I’ll keep it as it is for now, however, I do find that MT8195 doesn’t exist in this dt-bindings which it should be, so there may be conflicts when this series is going to be merged.

Don't top post. No, rebase on current next and implement my comment. Best regards, Krzysztof

Because MT8188 Merge is fully compatible with MT8195, we didn't add its
compatible name to the driver, but just list it in dt-bindings, and use
MT8195's compatible name to match the ID in device table. For example,
in mt8188.dtsi:
merge1: merge@1c10c000 {
compatible = "mediatek,mt8188-disp-merge", "mediatek,mt8195-
disp-merge";
...
};
If we add MT8188 Merge as an enum with MT8173, then our device tree
must be as below, and nothing will match in Merge driver.
merge1: merge@1c10c000 {
compatible = "mediatek,mt8188-disp-
merge";
...
};

Will rebase linux-next in the next version.

No, why? It would be incorrect with existing bindings. Again, on what
tree are you working?

Rebase now - for this discussion.

Just sent a v3 that is based on next-20230616 tag of linux-next/master
branch. After checking, still not sure what is the difference between
this modification and the others in mdp-rdma and ethdr. Could you share
more information please?

Done. Please refer to v3.
