[PATCH v8 04/10] arm: dts: sunxi: h3/h5: represent the mdio switch used by sun8i-h3-emac

From: Corentin Labbe
Date: Mon Oct 23 2017 - 15:02:26 EST


Since dwmac-sun8i could use either an integrated PHY or an external PHY
(which could be at same MDIO address), we need to represent this selection
by a MDIO switch.
