But it will negate a possible future SoC where an external PHY use the same phy mode than the integrated one. This patchs series adds a new way to find if the PHY is integrated, via the phy-is-integrated DT property. Since it exists both integrated and external ethernet-phy@1, they are merged in the final DTB and so share all properties. For avoiding this, and better represent the reality, we use a MDIO mux. Note that sun8i-v3s-emac have also an integrated PHY, but since it lacks any external PHY support, it is not necessary to add MDIO mux to it. The first patch should go via the sunxi tree. Note that this serie will need backporting the patch "Documentation: net: phy: Add phy-is-integrated binding" which is in net-next Thanks Regards Changes since v2: - Add a MDIO mux for creating distinction between integrated and external MDIO. - phy-is-integrated is not set in dtsi. Changes since v1: - Dropped phy-is-integrated documentation patch since another same patch was already merged - Moved phy-is-integrated from SoC dtsi to final board DT.
