So your reply where you basically stated that all the RGMII.*DLINE.*
constants here should be the same was nonsense. How can we trust your
replies?

Maybe Andrew can confirm, but this function was to fix up existing
broken DT, and shouldn't be used by brand new drivers.

As stated on the previous series, please don't abuse clk_tx_i for
soemthing that isn't the dwmac's clk_tx_i signal.
