The FEC driver ignores the polarity of phy-reset-gpios and it assumes the GPIO reset as active low. If it really is active high, then you would need to pass the "phy-reset-active-high" property. > +/ { > + model = "Y Soft IOTA Draco i.MX6Solo board"; > + compatible = "ysoft,imx6dl-yapp4-draco", "fsl,imx6dl"; > + > + cpus { > + /delete-node/ cpu@1; Is this really needed? We don't usually do this on imx6solo dts board files. Only one CPU will be brought up online on imx6solo anyway. > + }; > + > + memory@10000000 { Need to pass "device_type = "memory";" > +/ { > + model = "Y Soft IOTA Hydra i.MX6DualLite board"; > + compatible = "ysoft,imx6dl-yapp4-hydra", "fsl,imx6dl"; > + > + memory@10000000 { Need to pass "device_type = "memory";" > + memory@10000000 { Need to pass "device_type = "memory";"
