From ae2291fbe0f9858d332423a97c6b09157005050f Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Tue, 14 Aug 2012 06:47:22 +0000 Subject: fm-eth: add function fm_info_get_phy_address() Function fm_info_get_phy_address() returns the PHY address for a given Fman port. This is handy when the MDIO code needs to fixup the Ethernet nodes in the device tree to point to PHY nodes for a specific PHY address.
