		Attention: The link partner must be configurable as slave otherwise
		no link will be established.

		KSZ9131:

		All skew control options are specified in picoseconds. The increment
		step is 100ps. Unlike KSZ9031, the values represent picoseccond delays.
		A negative value can be assigned as rxc-skew-psec = <(-100)>;.

		Optional properties:

		Range of the value -700 to 2400, default value 0:

		- rxc-skew-psec : Skew control of RX clock pad
		- txc-skew-psec : Skew control of TX clock pad

		Range of the value -700 to 800, default value 0:

		- rxdv-skew-psec : Skew control of RX CTL pad
		- txen-skew-psec : Skew control of TX CTL pad
		- rxd0-skew-psec : Skew control of RX data 0 pad
		- rxd1-skew-psec : Skew control of RX data 1 pad
		- rxd2-skew-psec : Skew control of RX data 2 pad
		- rxd3-skew-psec : Skew control of RX data 3 pad
		- txd0-skew-psec : Skew control of TX data 0 pad
