MT8195 is an ARM platform SoC which has the same PCIe IP with MT8192.If it is the same, then 8192 should be a fallback compatible. 'The same' means the current driver for 8192 will work unchanged.
Hi Rob, Thanks for your review. Yes, the controller driver works fine in the MT8195 platform without any change, and we would like to use the compatible string in device tree as follows: "mediatek,mt8195-pcie", "mediatek,mt8192-pcie" Thanks.
