+Fixed link Device Tree binding
+------------------------------
+
+Some Ethernet MACs have a "fixed link", and are not connected to a
+normal MDIO-managed PHY device. For those situations, a Device Tree
+binding allows to describe a "fixed link".
+
+Such a fixed link situation is described by creating a 'fixed-link'
+sub-node of the Ethernet MAC device node, with the following
+properties:
+
+* 'speed' (integer, mandatory), to indicate the link speed. Accepted
+ values are 10, 100 and 1000
+* 'full-duplex' (boolean, optional), to indicate that full duplex is
+ used. When absent, half duplex is assumed.
+* 'pause' (boolean, optional), to indicate that pause should be
+ enabled.
+* 'asym-pause' (boolean, optional), to indicate that asym_pause should
+ be enabled.
+
+Examples:
+
+ethernet@0 {
+ ...
+ fixed-link {
+ speed = <1000>;
+ full-duplex;
+ };
+ ...
+};
