MT8195 is an ARM platform SoC which has the same PCIe IP with MT8192.

I thought you wanted to support 8192 as the fallback:

compatible = "mediatek,mt8195-pcie", "mediatek,mt8192-pcie";

The above schema doesn't allow this.

Hi Rob,

Yes, I want this fallback to support MT8195, but there are some un-
documented warnings if I don't add its compatible string to the yaml
file.

Do you have any suggestions in this case?

Thanks.
