To manage this regulator on Ethernet glue, I based my work on the examples of :   - allwinner,sun4i,   - allwinner,sun7i   - allwinner,sun8i   - fsl,fec   - rockchip-dwmac   - rockchip,emac For me it is normal that PHY Ethernet regulator is managed by MAC glue because it is mandatory to power ON Ethernet PHY chip BEFORE MDIO scan. Let me know if that works for you Regards, Christophe.
