X-Git-Tag: v6.19-rc5~17^2~1^2~2 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c63749a7ddc59ac6ec0b05abfa0a21af9f2c1d38;p=thirdparty%2Flinux.git arm64: dts: imx8mp: Fix LAN8740Ai PHY reference clock on DH electronics i.MX8M Plus DHCOM Add missing 'clocks' property to LAN8740Ai PHY node, to allow the PHY driver to manage LAN8740Ai CLKIN reference clock supply. This fixes sporadic link bouncing caused by interruptions on the PHY reference clock, by letting the PHY driver manage the reference clock and assure there are no interruptions. This follows the matching PHY driver recommendation described in commit bedd8d78aba3 ("net: phy: smsc: LAN8710/20: add phy refclk in support") Fixes: 8d6712695bc8 ("arm64: dts: imx8mp: Add support for DH electronics i.MX8M Plus DHCOM and PDK2") Signed-off-by: Marek Vasut Tested-by: Christoph Niedermaier Signed-off-by: Shawn Guo --- diff --git a/arch/arm64/boot/dts/freescale/imx8mp-dhcom-som.dtsi b/arch/arm64/boot/dts/freescale/imx8mp-dhcom-som.dtsi index 68c2e0156a5c..f8303b7e2bd2 100644 --- a/arch/arm64/boot/dts/freescale/imx8mp-dhcom-som.dtsi +++ b/arch/arm64/boot/dts/freescale/imx8mp-dhcom-som.dtsi @@ -113,6 +113,7 @@ ethphy0f: ethernet-phy@1 { /* SMSC LAN8740Ai */ compatible = "ethernet-phy-id0007.c110", "ethernet-phy-ieee802.3-c22"; + clocks = <&clk IMX8MP_CLK_ENET_QOS>; interrupt-parent = <&gpio3>; interrupts = <19 IRQ_TYPE_LEVEL_LOW>; pinctrl-0 = <&pinctrl_ethphy0>;
