For Jetson Xavier the internal -PHY RX and TX delay should be used and so fix this by setting the -'phy-mode' to 'rgmii-id' and not 'rgmii'. - -Cc: stable@vger.kernel.org - -Signed-off-by: Jon Hunter <jonathanh@nvidia.com> ---- - arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - -diff --git a/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi b/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi -index 623f7d7d216b..8e3136dfdd62 100644 ---- a/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi -+++ b/arch/arm64/boot/dts/nvidia/tegra194-p2888.dtsi -@@ -33,7 +33,7 @@ - - phy-reset-gpios = <&gpio TEGRA194_MAIN_GPIO(G, 5) GPIO_ACTIVE_LOW>; - phy-handle = <&phy>; -- phy-mode = "rgmii"; -+ phy-mode = "rgmii-id"; - - mdio { - #address-cells = <1>; |
