From 7a4e95d68970d5a3e0e3da45de56e91e1c61a07e Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Tue, 11 May 2021 06:37:35 +0200 Subject: ARM: imx7d: remove Atheros AR8031 PHY fixup This fixup configures the IO voltage and disables the SmartEEE functionality. If this patch breaks your system, enable AT803X_PHY driver and configure the PHY by the device tree: phy-connection-type = "rgmii-id"; ethernet-phy@X { reg = <0xX>; qca,smarteee-tw-us-1g = <24>; vddio-supply = <&vddh>; vddio: vddio-regulator { regulator-name = "VDDIO"; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; }; vddh: vddh-regulator { regulator-name = "VDDH"; }; }; Signed-off-by: Oleksij Rempel Reviewed-by: Andrew Lunn Signed-off-by: Shawn Guo --- arch/arm/mach-imx/mach-imx7d.c | 22 ---------------------- 1 file changed, 22 deletions(-) diff --git a/arch/arm/mach-imx/mach-imx7d.c b/arch/arm/mach-imx/mach-imx7d.c index 879c35929a13..ccf64ddf8b7e 100644 --- a/arch/arm/mach-imx/mach-imx7d.c +++ b/arch/arm/mach-imx/mach-imx7d.c @@ -14,25 +14,6 @@ #include "common.h" -static int ar8031_phy_fixup(struct phy_device *dev) -{ - u16 val; - - /* Set RGMII IO voltage to 1.8V */ - phy_write(dev, 0x1d, 0x1f); - phy_write(dev, 0x1e, 0x8); - - /* disable phy AR8031 SmartEEE function. */ - phy_write(dev, 0xd, 0x3); - phy_write(dev, 0xe, 0x805d); - phy_write(dev, 0xd, 0x4003); - val = phy_read(dev, 0xe); - val &= ~(0x1 << 8); - phy_write(dev, 0xe, val); - - return 0; -} - static int bcm54220_phy_fixup(struct phy_device *dev) { /* enable RXC skew select RGMII copper mode */ @@ -44,14 +25,11 @@ static int bcm54220_phy_fixup(struct phy_device *dev) return 0; } -#define PHY_ID_AR8031 0x004dd074 #define PHY_ID_BCM54220 0x600d8589 static void __init imx7d_enet_phy_init(void) { if (IS_BUILTIN(CONFIG_PHYLIB)) { - phy_register_fixup_for_uid(PHY_ID_AR8031, 0xffffffff, - ar8031_phy_fixup); phy_register_fixup_for_uid(PHY_ID_BCM54220, 0xffffffff, bcm54220_phy_fixup); } -- cgit
