Old imx6q machine code makes RGMII/RMII clock direction decision based on configuration of "ptp" clock. "enet_out" is not used and make no real sense, since we can't configure it as output or use it as clock provider. Instead of "enet_out" use "enet_clk_ref" which is actual selector to choose between internal and external clock source: FEC MAC <---------- enet_clk_ref <--------- SoC PLL \ ^------<-> refclock PAD (bi directional) Signed-off-by: Oleksij Rempel <o.rempel@xxxxxxxxxxxxxx> --- arch/arm/boot/dts/imx6qdl.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm/boot/dts/imx6qdl.dtsi b/arch/arm/boot/dts/imx6qdl.dtsi index ff1e0173b39b..71522263031a 100644 --- a/arch/arm/boot/dts/imx6qdl.dtsi +++ b/arch/arm/boot/dts/imx6qdl.dtsi @@ -1050,8 +1050,8 @@ fec: ethernet@2188000 { clocks = <&clks IMX6QDL_CLK_ENET>, <&clks IMX6QDL_CLK_ENET>, <&clks IMX6QDL_CLK_ENET_REF>, - <&clks IMX6QDL_CLK_ENET_REF>; - clock-names = "ipg", "ahb", "ptp", "enet_out"; + <&clks IMX6QDL_CLK_ENET_REF_SEL>; + clock-names = "ipg", "ahb", "ptp", "enet_clk_ref";
Please also update fec binding, otherwise there will be dtbs check error. Thanks, Peng.
