From bc3410f250219660a7be032c01c954a53b2c26ab Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 4 Aug 2022 10:36:04 -0700 Subject: [PATCH] net: bcmgenet: Indicate MAC is in charge of PHY PM Avoid the PHY library call unnecessarily into the suspend/resume functions by setting phydev->mac_managed_pm to true. The GENET driver essentially does exactly what mdio_bus_phy_resume() does by calling phy_init_hw() plus phy_resume().
