Hm, to me that's confusing. What about: "mediatek,mt7623-btif": for MediaTek MT7623 "mediatek,mt7622-btif", "mediatek,mt7623-btif": for MediaTek MT7622 If in the future we have more SoCs that support the BTIF, we should add them like the mt7622 case. Make sense?

The reason i don't add it as usual is the following. 8250.txt is common and shared among all uart like devices, so i don't want btif device occupies too much section and bloat the document when every new MediaTek SoC is introduced. So instead I refer to existing Nvidia device added in 8250.txt which I thought its way is simple, elegant and also using pattern I can use to add btif devices.
