-Fixed link Device Tree binding
2
-------------------------------
3
-
4
-Some Ethernet MACs have a "fixed link", and are not connected to a
5
-normal MDIO-managed PHY device. For those situations, a Device Tree
6
-binding allows to describe a "fixed link".
7
-
8
-Such a fixed link situation is described by creating a 'fixed-link'
9
-sub-node of the Ethernet MAC device node, with the following
10
-properties:
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.
20
-* 'link-gpios' ('gpio-list', optional), to indicate if a gpio can be read
21
-  to determine if the link is up.
22
-
23
-Old, deprecated 'fixed-link' binding:
24
-
25
-* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the
26
-  form <a b c d e> with the following accepted values:
27
-  - a: emulated PHY ID, choose any but but unique to the all specified
28
-    fixed-links, from 0 to 31
29
-  - b: duplex configuration: 0 for half duplex, 1 for full duplex
30
-  - c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000
31
-  - d: pause configuration: 0 for no pause, 1 for pause
32
-  - e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for
33
-    asymmetric pause
34
-
35
-Examples:
36
-
37
-ethernet@0 {
38
-	...
39
-	fixed-link {
40
-	      speed = <1000>;
41
-	      full-duplex;
42
-	};
43
-	...
44
-};
45
-
46
-ethernet@1 {
47
-	...
48
-	fixed-link {
49
-	      speed = <1000>;
50
-	      pause;
51
-	      link-gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>;
52
-	};
53
-	...
54
-};
