> Unfortunately, it's not enough to just move DT parsing code to .probe() as
> it depends on phydev->interface value, which is set to correct value abter
> the .probe() is completed and before calling .config_init(). So, RGMII
> configuration can't be loaded from DT.
> To fix and issue
> - move RGMII validation code to .config_init()
> - parse RGMII parameters in dp83867_of_init(), but consider them as
> optional.
