It's not exactly about the wording but the concept. We don't have generic devices, thus no generic DT (DTS). Period.

You now say that these are valid boards: compatible = "google,gs101", "google,gs101"; (although compatibles compatible = "google,gs101", "google,gs101-pixel"; Both are wrong. SoC should not be before the board and SoC cannot be used alone. Your schema allows that and that's not good. I did not get what you want to achieve here, so tricky to advice. Best regards, Krzysztof
