dt-bindings: fec: explicitly mark deprecated properties

- phy-mode : See ethernet.txt file in the same directory

Optional properties:

- phy-reset-gpios : Should specify the gpio for phy reset

- phy-reset-duration : Reset duration in milliseconds.  Should present

  only if property "phy-reset-gpios" is available.  Missing the property

  will have the duration be 1 millisecond.  Numbers greater than 1000 are

  invalid and 1 millisecond will be used instead.

- phy-reset-active-high : If present then the reset sequence using the GPIO

  specified in the "phy-reset-gpios" property is reversed (H=reset state,

  L=operation state).

- phy-reset-post-delay : Post reset delay in milliseconds. If present then

  a delay of phy-reset-post-delay milliseconds will be observed after the

  phy-reset-gpios has been toggled. Can be omitted thus no delay is

  observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.

- phy-supply : regulator that powers the Ethernet PHY.

- phy-handle : phandle to the PHY device connected to this device.

- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.

  For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse

  per second interrupt associated with 1588 precision time protocol(PTP).

Optional subnodes:

- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes

  according to phy.txt in the same directory

Deprecated optional properties:

	To avoid these, create a phy node according to phy.txt in the same

	directory, and point the fec's "phy-handle" property to it. Then use

	the phy's reset binding, again described by phy.txt.

- phy-reset-gpios : Should specify the gpio for phy reset

- phy-reset-duration : Reset duration in milliseconds.  Should present

  only if property "phy-reset-gpios" is available.  Missing the property

  will have the duration be 1 millisecond.  Numbers greater than 1000 are

  invalid and 1 millisecond will be used instead.

- phy-reset-active-high : If present then the reset sequence using the GPIO

  specified in the "phy-reset-gpios" property is reversed (H=reset state,

  L=operation state).

- phy-reset-post-delay : Post reset delay in milliseconds. If present then

  a delay of phy-reset-post-delay milliseconds will be observed after the

  phy-reset-gpios has been toggled. Can be omitted thus no delay is

  observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.
