You could refer to the following section in arch/arm64/boot/dts/freescale/qoriq-fman3-0.dtsi.

ptp_timer0: ptp-timer@1afe000 {
              compatible = "fsl,fman-ptp-timer", "fsl,fman-rtc";
              reg = <0x0 0x1afe000 0x0 0x1000>;

              clocks = <&clockgen 3 0>;
              fsl,extts-fifo;
};

fsl-ls1046-post.dtsi includes qoriq-fman3-0.dtsi, just including fsl-ls1046-post.dtsi in your dts file and enable CONFIG_FSL_SDK_FMAN_RTC_API to check whether it could work normally.

You have a dts file for testing. . ?

hi yipingwang

When uboot starts, how do you decide to use that DTS?
