On most of the Amlogic SoC I observed that Ethernet would not get
initialize when try to deploy the mainline kernel, earlier I tried to
fix this issue with by setting ethernet reset but it did not resolve
the issue see below.
	resets = <&reset RESET_ETHERNET>;
	reset-names = "stmmaceth";

After checking what was the missing with Rockchip SoC dts
I tried to add this missing compatible string and then it
started to working on my setup.

Also I tried to fix the device tree binding to validate the changes.

Tested this on my Odroid-N2 and Odroid-C2 (64 bit) setup.
I do not have ready Odroid C1 (32 bit) setup so please somebody test.

When working on the Odroid-C2 I did not have such a problem.
And if you look at of_mdiobus_child_is_phy() and
of_mdiobus_register_phy() you'll see that your change shouldn't be
needed.

Could you please elaborate on:
- What is the exact problem you're facing? Best add a dmesg log.
- Which kernel version are you using?

Best Regards
-Anand
