From f3dd213e151ece2a382e730f5e75156536b2419d Mon Sep 17 00:00:00 2001 From: Marek Behún Date: Thu, 7 Apr 2022 00:32:57 +0200 Subject: net: introduce helpers to get PHY ofnode from MAC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add helpers ofnode_get_phy_node() and dev_get_phy_node() and use it in net/mdio-uclass.c function dm_eth_connect_phy_handle(). Also add corresponding UT test. This is useful because other part's of U-Boot may want to get PHY ofnode without connecting a PHY.
