Disable SSC(Spread Spectrum Cloclk) for PCIe debugging

Hello,

We want to control REFCLK manually as the link.

+       clocks {

+               clock@pllnvhs {

+                       clk-id = ;

+                       /* disable ssc on PLLNVHS */

+                       pll_freq_table = <38400000 100000000 2 125 24 (-1) (-1) (-1) (-1)>;

+               };

+       };

There is no “tegra194-bpmp-p2888-uphy.dtsi” file under kernel source.

So, we modify 2 files as below :
Linux_for_Tegra/bootloader/tegra194-a02-bpmp-p2888-0008-b01-jaxi.dtb
Linux_for_Tegra/bootloader/t186ref/tegra194-a02-bpmp-p2888-0008-b01-jaxi.dtb

tegra194-a02-bpmp-p2888-0008-b01-jaxi.dtb (174.4 KB)
tegra194-a02-bpmp-p2888-0008-b01-jaxi.dts (272.3 KB)

Would it apply, if i flash jetson as below :
sudo ./flash.sh jetson-agx-xavier-industrial mmcblk0p1

And could I check does it apply or not?
