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.
