It sounds like you need to add appropriate pull-ups/pull-downs on the
iMX6 configure the phy.  This is why imx6qdl-microsom-ar8035.dtsi has
different settings from the normal RGMII pullups/downs - in the case
of AR8035, a number of pins including the receive pins determine reset
options.  See the comments in that file concerning "pin strapping".
