iMX8 Nano Kernel updation from 5.15 to 6.18

Hi 

While porting the kernel from 5.15 to 6.18 for the A53 core. facing an issue with rpmsg.
 # dmesg -T | grep -Ei 'rpmsg|rproc'
[Tue Oct 8 15:42:28 2024] imx rpmsg driver is registered.
[Tue Oct 8 15:42:29 2024] imx-rproc imx8mn-cm7: error -ENOENT: Failed to enable clock
[Tue Oct 8 15:42:29 2024] imx-rproc imx8mn-cm7: probe with driver imx-rproc failed with error -2
[Tue Oct 8 15:42:29 2024] remoteproc remoteproc0: releasing imx-rproc

I am getting this error.When i searched this error online i was asked to add dummy clock in the dts as below
 imx8mn-cm7 {
    compatible = "fsl,imx8mn-cm7";
    rsc-da = <0xb8000000>;
    clocks = <&clk IMX8MN_CLK_DUMMY>;
    mbox-names = "tx", "rx", "rxdb";
    mboxes = <μ 0 1
                                   μ 1 1
                                   μ 3 1>;
    memory-region = <&vdevbuffer>, <&vdev0vring0>, <&vdev0vring1>, <&rsc_table>;
    status = "okay";
  }
Could u please let me is this the only the change required. What is the reason for this change.
