Can someone, please, provide a sample or template device tree file that I can use for DP83TG720R-Q1?

Gerome, is this the relevant block that we need?

&davinci_mdio {
	phy0: ethernet-phy@0 {
		reg = <0>;
		ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>;
		ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
	};
};

And include the DaVinci driver in our kernel configuration? We have patched in the driver from: git.ti.com/gitweb

Hi Warren,

For a sample device tree, what is needed is:

&ARB_NAME {

ARB_NAME_1: ethernet-phy@PHY_ADDRESS {

reg = <PHY_ADDRESS>;

};

ARB_NAME and ARB_NAME_1 will depend on your hardware and it is best to consult with manufacturer. PHY_ADDRESS will be the strapped address of PHY; usually an int.

Sincerely,

Gerome
