dt-bindings: net: Add YAML schemas for the generic Ethernet options
The Ethernet controllers have a good number of generic options that can be
needed in a device tree. Add a YAML schemas for those.

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. -* 'link-gpios' ('gpio-list', optional), to indicate if a gpio can be read - to determine if the link is up. - -Old, deprecated 'fixed-link' binding: - -* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the - form <a b c d e> with the following accepted values: - - a: emulated PHY ID, choose any but but unique to the all specified - fixed-links, from 0 to 31 - - b: duplex configuration: 0 for half duplex, 1 for full duplex - - c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000 - - d: pause configuration: 0 for no pause, 1 for pause - - e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for - asymmetric pause - -Examples: - -ethernet@0 { - ... - fixed-link { - speed = <1000>; - full-duplex; - }; - ... -}; - -ethernet@1 { - ... - fixed-link { - speed = <1000>; - pause; - link-gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>; - }; - ... -}; +This file has moved to ethernet-controller.yaml. |
