-Subject: [PATCH 1/3] dt-bindings: net: ipq4019-mdio: document now supported
|
|
|
- clock-frequency
|
|
|
-
|
|
|
-Document support for clock-frequency and add details on why this
|
|
|
-property is needed and what values are supported.
|
|
|
-
|
|
|
-From internal documentation, while other values are supported, the
|
|
|
-correct function of the MDIO bus is not assured hence add only the
|
|
|
-suggested supported values to the property enum.
