PetaLinux - Zynq MPSoC PS-GTR SGMII - fixed link support patch

Description

The attached patch enables PS-GTR SGMII to initialize dependent on the is-internal-pcspma property rather than the PHY mode.

This is to support PS-GTR SGMII to SGMII fixed link without PHY.

Solution

Please find the patches attached for the 2017.1 and 2018.1 version respectively.

Example DTS:

&gem2 {
    local-mac-address = [DE AD BE FF 01 01];
        is-internal-pcspma;
        phy-mode = "moca";
        fixed-link {
          speed = <1000>;
          full-duplex;
    };
};


Note: These patches are versions dependent.

You will need the patch for all versions. For other versions, you can make manual modifications to the kernel source or create a patch based on it before building the project.
