I guess this one should go in .Documentation/devicetree/bindings/rtc/trivial-rtc.yaml?

Thank you for your patch. There is something to discuss/improve.

Why only one compatible? What about ep9307 and ep9312? The same question
for your previous patch - timer.

Anyway, if you want to keep it like that, then filename should match
compatible. Or merge it into trivial-rtc like Alexandre suggested.

Best regards,
Krzysztof

If you add missing compatibles, you won't be able to move it easily to
trivial-rtc.
