… phy-vreg
The staging overlay used a bare "/ {" root node block to define the
qep_vreg and aqr_vreg fixed regulators. In a DT overlay, a bare "/ {"
creates a new root fragment that is not merged into the base tree's
root node; as a result the regulator nodes are never instantiated and
the tc956x driver cannot resolve the phy-supply phandle, leading to a
failed MDIO probe:
tc956x_pci-eth 0001:05:00.1: No PHY found
Replace "/ {" with the overlay-correct "&{/} {" syntax so that the
fragment is properly applied as an amendment to the base device-tree
root node. This ensures the regulator nodes are present at boot and
the PHY powers up correctly.
