Commit Message

The AST2600 splits out the MDIO bus controller from the MAC into its own
IP block and rearranges the register layout. Add a new binding to
describe the new hardware.

Should have a:

Then you can drop these 2.

And this.

This isn't specific to ASpeed either and is already covered by
ethernet-phy.yaml.

So that means none of the child node schema is needed here.

Don't show status in examples.

Sorry, copy/paste at fault.

Thanks for the feedback.
