The bootloader does not always initialize the MDIO pins before booting Linux. E.g. on version "U-Boot 2012.07 [Chaos Calmer 15.05.1,r35193] (Jul 25 2017 - 11:36:26)" this is the case when booting automatically without activating the U-Boot console. Without this change, the kernel boot will complain about missing PHYs: libphy: ipq40xx_mdio: probed ar40xx c000000.ess-switch: Probe failed - Missing PHYs! libphy: Fixed MDIO Bus: probed With this change it will work as expected: libphy: ipq40xx_mdio: probed ESS reset ok! ESS reset ok! libphy: Fixed MDIO Bus: probed Ref: GH-2835 Tested-by: Fredrik Olofsson <fredrik.olofsson@anyfinetworks.com> Signed-off-by: Leon M.
