* net: designware: Fix for use with current Linux device tree for Meson GXHeiner Kallweit2017-02-07-0/+1
| | | | | | | | | | | | | | | | In Uboot for Meson GX the compatible string in meson-gxbb.dtsi so far is: compatible = "amlogic,meson6-dwmac", "snps,dwmac"; On Linux in the same dt file it's compatible = "amlogic,meson-gx-dwmac", "amlogic,meson-gxbb-dwmac", "snps,dwmac"; To avoid breaking ethernet with the next DT synch from Linux to U-Boot (planned as prerequisite for adding Meson GX MMC driver to U-Boot) add "amlogic,meson-gx-dwmac" to the compatibility list in the designware driver.

| | | | | | | | | | | | | | Commit 79e86ccb3786c8b20004db3fa10a70049456f580 "vitesse: remove duplicated argument to ||" correctly removed a redundant check. However, I believe that the original code was simply wrong, and should have been checking against RGMII_ID.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixup port_mac_address property in MC DPC with values from the u-boot environment. Since u-boot already reads the environment MAC addresses when probing the PHYs, use these values. The u-boot environment MAC addresses take precedence over any eventual ones defined in the DPC, except for the case where they are randomly assigned (no u-boot env value declared for port). The patch assumes the "/board_info/ports/" node is present in the DPC.
