From 86f6cf41272de9d6ffa05ab46028b15d160a6f3e Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Sat, 24 May 2014 09:34:26 +0200 Subject: net: of_mdio: add of_mdiobus_link_phydev() Add a function to walk the list of subnodes of a mdio bus and look for a node that matches the phy's address with its 'reg' property. If found, set the of_node pointer for the phy. This allows auto-probed pyh devices to be augmented by information passed in via DT.
