1 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 21 Examples: 22 23 ethernet@0 { 24 ... 25 fixed-link { 26 speed = <1000>; 27 full-duplex; 28 }; 29 ... 30 }; 31
