From 18c60b383df3d7e36f7330e9092da87a87523c0e Mon Sep 17 00:00:00 2001 From: Sergiu Moga Date: Wed, 19 Oct 2022 15:09:32 +0300 Subject: [PATCH] net: macb: Specify PHY PM management done by MAC [ Upstream commit 15a9dbec631cd69dfbbfc4e2cbf90c9dd8432a8f ] The `macb_resume`/`macb_suspend` methods already call the `phylink_start`/`phylink_stop` methods during their execution so explicitly say that the PM of the PHY is done by MAC by using the `mac_managed_pm` flag of the `struct phylink_config`. This also fixes the warning message issued during resume: WARNING: CPU: 0 PID: 237 at drivers/net/phy/phy_device.c:323 mdio_bus_phy_resume+0x144/0x148 Depends-on: 96de900ae78e ("net: phylink: add mac_managed_pm in phylink_config structure") Fixes: 744d23c71af3 ("net: phy: Warn about incorrect mdio_bus_phy_resume() state") Signed-off-by: Sergiu Moga Reviewed-by: Florian Fainelli Reviewed-by: Claudiu Beznea Link: https://lore.kernel.org/r/20221019120929.63098-1-sergiu.moga@microchip.com Signed-off-by: Jakub Kicinski Signed-off-by: Sasha Levin --- drivers/net/ethernet/cadence/macb_main.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/ethernet/cadence/macb_main.c b/drivers/net/ethernet/cadence/macb_main.c index 3ca3f9d..61efb23 100644 --- a/drivers/net/ethernet/cadence/macb_main.c +++ b/drivers/net/ethernet/cadence/macb_main.c @@ -880,6 +880,7 @@ static int macb_mii_probe(struct net_device *dev) bp->phylink_config.dev = &dev->dev; bp->phylink_config.type = PHYLINK_NETDEV; + bp->phylink_config.mac_managed_pm = true; if (bp->phy_interface == PHY_INTERFACE_MODE_SGMII) { bp->phylink_config.poll_fixed_state = true; -- 2.7.4
