The binding incorrectly described only a single generic supply via 'phy-supply'. Deprecate 'phy-supply' and instead add two named supply properties. The 0.9V rail draws a peak current of 46 mA and the 1.2V rail draws 15 mA.

Without them: qcom-dwmac-sgmii-phy 8909000.phy: QSERDES_COM_C_READY_STATUS timed-out qcom-ethqos 23040000.ethernet eth0: __stmmac_open: Serdes powerup failed The driver relied solely on the PHY framework's implicit enable of 'phy-supply', which only voted for a single rail and set no current load. Use devm_regulator_bulk_get_const() to acquire both supplies and set the peak current loads (46 mA for vdda-0p9, 15 mA for vdda-1p2) as required by the hardware.

The PHY requires vdda-0p9 (vreg_l4a) and vdda-1p2 (vreg_l1c). Replace the incorrect phy-supply with these two named properties on both the base EVK node and the IFP mezzanine overlay.
