Optional properties:

Example:

Do we need to add new added entries in the example section as well.

E.g.

+        phy-enable-gpios = <&gpio1 4 0>; /* GPIO1_4, active high*/
+        phy-standby-gpios = <&gpio1 2 1>; /* GPIO1_2, active low */

I chose not to because after all these two are optional properties.

1: If you use a facility then #include the file that defines/declares
   that facility.  Don't depend on other header files pulling in ones
   that you use.
