From a9f6309585cbefa4a7f08c9017ca482c3222323a Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 22 Aug 2014 18:55:44 -0700 Subject: [PATCH] net: phy: allow phy_init_eee() to work with internal PHYs Internal PHYs do not have any specific phy_interface_t defined because they are within an Ethernet MAC or a larger IC, they will fail the early check in phy_init_eee(). Allow these PHYs to proceed with EEE initialization and report error/success by checking the standard C45 EEE-related registers. Signed-off-by: Florian Fainelli Signed-off-by: David S.
