Any properties related to this integration can be included in the .dtsi file, instead of having board dts files specify them separately. Add the clock_in_out property to specify the direction of the PHY clock. This is the minimum required to have gmac2phy working on Linux. Other examples include assigned-clocks, assigned-clock-rates, and assigned-clock-parents properties, but the hardware default plus the implementation requesting the appropriate clock rate also works.
