André Draszik 9846a4524a ARM: dts: imx7d: cl-som-imx7: make ethernet work again ... Recent changes to the atheros at803x driver caused ethernet to stop working on this board. In particular commit 6d4cd041f0 ("net: phy: at803x: disable delay only for RGMII mode") and commit cd28d1d6e5 ("net: phy: at803x: Disable phy delay for RGMII mode") fix the AR8031 driver to configure the phy's (RX/TX) delays as per the 'phy-mode' in the device tree. This now prevents ethernet from working on this board. It used to work before those commits, because the AR8031 comes out of reset with RX delay enabled, and the at803x driver didn't touch the delay configuration at all when "rgmii" mode was selected, and because arch/arm/mach-imx/mach-imx7d.c:ar8031_phy_fixup() unconditionally enables TX delay. Since above commits ar8031_phy_fixup() also has no effect anymore, and the end-result is that all delays are disabled in the phy, no ethernet. Update the device tree to restore functionality.
