AM3359: MII mode not functional on 5.4rt kernel and AM3359

Hello Annapurna,

Thank you for the follow-up query.

Please expect delay in response due to the upcoming US holiday.

Are you testing this on an EVM or a custom board.?

Hi Srinivas,

Thank you for the response.

We are working on the custom hardware. We want to use MII instead of RG-MII.

Thanks,

Hello Annapurna, 

Thank you for the input. 

I would assume that the hardware connections between the processor and the PHY has been checked to be as per the requirement.

Yes, The Hardware connections are in place, as this was working seamlessly with kernel 4.9rt.

Please find the node:

&mac {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&cpsw_default>;
pinctrl-1 = <&cpsw_sleep>;
status = "okay";
dual_emac;
};

&davinci_mdio {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&davinci_mdio_default>;
pinctrl-1 = <&davinci_mdio_sleep>;
status = "okay";

ethphy0: ethernet-phy@1 {
reg = <1>;
};

ethphy1: ethernet-phy@3 {
reg = <3>;
};

};

&cpsw_emac0 {
phy-handle = <&ethphy0>;
phy-mode = "mii";
dual_emac_res_vlan = <1>;
};

&cpsw_emac1 {
phy-handle = <&ethphy1>;
phy-mode = "mii";
dual_emac_res_vlan = <2>;
};

Hello Annapurna, 

Thank you for confirming and noted.

Please expect a delay in response due to  upcoming US holiday.
