From e2eb83a0f829d42e13ed2bb41e97311e40d3adf9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Lothar=20Wa=C3=9Fmann?= Date: Tue, 24 Oct 2017 15:18:22 +0200 Subject: [PATCH] ARM: dts: imx6ul-txul: specify ethernet phy reset post-delay Under certain circumstances the ethernet PHY cannot be detected on Ka-Ro electronics TXUL modules. Using a phy-reset-post-delay of > 5ms alleviates this problem. Specify a value of 10ms to be on the safe side. --- arch/arm/boot/dts/imx6ul-tx6ul.dtsi | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm/boot/dts/imx6ul-tx6ul.dtsi b/arch/arm/boot/dts/imx6ul-tx6ul.dtsi index d30c4e05e624..9e2a96617d5b 100644 --- a/arch/arm/boot/dts/imx6ul-tx6ul.dtsi +++ b/arch/arm/boot/dts/imx6ul-tx6ul.dtsi @@ -308,6 +308,7 @@ pinctrl-0 = <&pinctrl_enet1 &pinctrl_enet1_mdio &pinctrl_etnphy0_rst>; phy-mode = "rmii"; phy-reset-gpios = <&gpio5 6 GPIO_ACTIVE_LOW>; + phy-reset-post-delay = <10>; phy-supply = <®_3v3_etn>; phy-handle = <&etnphy0>; status = "okay"; -- 2.39.2
