enable-active-high should only be used when there is a corresponding
gpio property.

This should be ACTIVE_LOW instead.

This is a deprecated property.

The recommendation is to add a mdio node with:

reset-gpios = <&gpio1 25 GPIO_ACTIVE_LOW>;
reset-assert-us = <10000>;

Is this an Atheros AR8031 PHY. If so, please check imx6qdl-sabresd.dtsi.

This is unused, drop it.

Please check commit ece1e4999 606 ("ASoC: fsl_ssi: Remove unneeded
'i2s-slave' property")

@0 and reg = <2> do not match.
