Icenowy Zheng 2f878491b3 net-next: stmmac: dwmac-sun8i: ensure the EPHY is properly reseted ... The EPHY may be already enabled by bootloaders which have Ethernet capability (e.g. current U-Boot). Thus it should be reseted properly before doing the enabling sequence in the dwmac-sun8i driver, otherwise the EMAC reset process may fail if no cable is plugged, and then fail the dwmac-sun8i probing. Tested on Orange Pi PC, One and Zero. All the boards fail to have dwmac-sun8i probed with "EMAC reset timeout" without cable plugged before, and with this fix they're now all able to successfully probe the EMAC without cable plugged and then use the connection after a cable is hot-plugged in.
