If you have occasion to post a v6, please:

- Update the subject line so it starts with a capital letter,
capitalizes "Airoha" appropriately, and includes "EN7523" as your
DT patch does, and moves those close to the beginning, e.g.,

PCI: mediatek: Allow selection for Airoha EN7532

- Update the commit log so it says what this patch does. It's OK to
repeat the subject line. Add a period at end.

I expected a patch to add "airoha,en7523-pcie" to
drivers/pci/controller/pcie-mediatek.c. Did I miss it?

Oh, I see your arch/arm/boot/dts/en7523.dtsi has:

+ pcie0: pcie@1fa91000 {
+ compatible = "airoha,en7523-pcie", "mediatek,mt7622-pcie";

so I guess you just rely on the existing "mediatek,mt7622-pcie" string
in the driver?
