| 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 |
| * '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 |
| * 'asym-pause' (boolean, optional), to indicate that asym_pause should |
