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;
|
||
|
};
|
||
|
...
|
||
|
};
