Hi,
Poco M3 (citrus) is same HW like Redmi 9T (lime) and Remi 9T NFC (lemon)
basically is
a lime with NFC.
So i think it would be better make a common base from lemon's devicetree
instead of making the same
devicetree again for the different variants where only the compatible
and the model property will be
the difference.
Check sm6125-xiaomi-gingkgo-common for example, it was the same case for
Redmi Note 8 (ginkgo) and 8T (willow).
