[PATCH V2] net: fec: Get rid of FEC_ENET_ENABLE_[TR]XC_DELAY

Marek Vasut marex at denx.de
Sun Jan 24 15:51:17 CET 2021


The FEC_ENET_ENABLE_.XC_DELAY setting is only used by one system which
supports OF control, correctly set the rgmii-id PHY mode in the DT and
then determine whether or not to enable the FEC RXC/TXC internal delay
based on the PHY mode.
