[PATCH 6/6] net: stmmac: revert "support future possible different internal phy mode"

Show all headers | View raw

Since internal phy-mode is reserved for non-xMII protocol we cannot use
it with dwmac-sun8i
This reverts commit 1c2fa5f84683 ("net: stmmac: support future possible different internal phy mode")
