I was looking at latest kernel code and it is designed differently there. https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/net/phy/dp83867.c?h=next-20200213#n479 there is if rgmii or sgmii if rgmii io impedance if sgmii in u-boot you have if rgmii if sgmii io impedance I am ok with having this in sync but that's not what we have today.
