Interesting. But the logs are showing accesses much more frequent
than once per second, it seems... (?)

And an interrupt for the PHY is configured in the device tree:

&eth0 {
        #address-cells = <1>;
        #size-cells = <0>;
        phy-connection-type = "rgmii";
        phy-handle = <&eth0_phy>;

        /* Atheros AR8035 */
        eth0_phy: ethernet-phy@4 {
                compatible = "ethernet-phy-id004d.d072",
                             "ethernet-phy-ieee802.3-c22";
                interrupts = <37 IRQ_TYPE_EDGE_RISING>;
                reg = <4>;
        };
};

I'll add a log for the request_irq call.

Regards.
