- 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;
- };
- ...
- };
