From b18b745397e0154795b2d5504def5ccd090b893c Mon Sep 17 00:00:00 2001 From: Alexander Kochetkov Date: Thu, 20 Apr 2017 16:29:34 +0300 Subject: net: arc_emac: switch to phy_start()/phy_stop() Currently driver use phy_start_aneg() in arc_emac_open() to bring up PHY. But phy_start() function is more appropriate for this purposes. Besides that it call phy_start_aneg() as part of PHY startup sequence it also can correctly bring up PHY from error and suspended states. So the patch replace phy_start_aneg() to phy_start(). Also the patch add call to phy_stop() to arc_emac_stop() to allow the PHY device to be fully suspended when the interface is unused.
