In case the i.MX8MP DHCOM rev.100 has been populated on the PDK3 carrier board, the on-SoM PHY PHYAD1 signal has been pulled high by the carrier board and changed the PHY MDIO address from 5 to 7. This has been fixed on production rev.200 SoM by additional buffer on the SoM PHYAD/LED signals, remove the workaround. Signed-off-by: Marek Vasut <marex@denx.de>
