The code in starfive_dwmac_fix_mac_speed() is a repeated pattern amongst many drivers, and having each platform driver re-implement this is not sane. Those who know me will know that I have a patch that cleans this all up - moving basically the guts of this to a library function which platform drivers can make use of.
It's not like the clock rates are somehow special - they're standard for 10M/100M/1G speeds on a GMII-family interface, and the 10M/100M also share the clock rates with MII.
