If this patch breaks your system, please enable AT803X_PHY driver and add the following device tree property to the PHY node: phy-mode = "rgmii-txid"; Signed-off-by: Oleksij Rempel --- arch/arm/mach-imx/mach-imx6q.c | 6 ------ 1 file changed, 6 deletions(-) diff --git a/arch/arm/mach-imx/mach-imx6q.c b/arch/arm/mach-imx/mach-imx6q.c index 78205f90da27..1abefe7e1c3a 100644 --- a/arch/arm/mach-imx/mach-imx6q.c +++ b/arch/arm/mach-imx/mach-imx6q.c @@ -82,12 +82,6 @@ static int ar8031_phy_fixup(struct phy_device *dev) val |= 0x18; phy_write(dev, 0xe, val); - /* introduce tx clock delay */ - phy_write(dev, 0x1d, 0x5); - val = phy_read(dev, 0x1e); - val |= 0x0100; - phy_write(dev, 0x1e, val); - return 0; }
