From: Florian Fainelli Date: Thu, 4 Aug 2022 17:36:04 +0000 (-0700) Subject: net: bcmgenet: Indicate MAC is in charge of PHY PM X-Git-Tag: v5.15.73~955 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eb2d9dc79f5f004342b0ed87ade67c4598b81c89;p=platform%2Fkernel%2Flinux-rpi.git net: bcmgenet: Indicate MAC is in charge of PHY PM commit bc3410f250219660a7be032c01c954a53b2c26ab upstream. 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().
