Shouldn't we rather move this into the PHY driver altogether ?
If I fix, the phydriver with empty function, compiler will complain about
unused parameter right?
What about other phy's which doesn't have this callback.
I mean, should we not move this entire code which configures something in a Micrel PHY, and is specific to Micrel PHY, into the Micrel PHY driver and remove the whole call of writeext from this ethernet driver ?
Ok , this function is invoked during data transfer. We could remove this function and test on all RCar boards to see any issues present or not? By looking at [1], only this driver is using writeext. [1]https://elixir.bootlin.com/u-boot/v2020.10-rc4/A/ident/writeext
