1Fixed link Device Tree binding
2------------------------------
3
4Some Ethernet MACs have a "fixed link", and are not connected to a
5normal MDIO-managed PHY device. For those situations, a Device Tree
6binding allows to describe a "fixed link".
7
8Such a fixed link situation is described by creating a 'fixed-link'
9sub-node of the Ethernet MAC device node, with the following
10properties:
11
12* 'speed' (integer, mandatory), to indicate the link speed. Accepted
13  values are 10, 100 and 1000
14* 'full-duplex' (boolean, optional), to indicate that full duplex is
15  used. When absent, half duplex is assumed.
16* 'pause' (boolean, optional), to indicate that pause should be
17  enabled.
18* 'asym-pause' (boolean, optional), to indicate that asym_pause should
19  be enabled.

24	...
25	fixed-link {
26	      speed = <1000>;
27	      full-duplex;
28	};
29	...
30};
