Disable Spread Spectrum (SSC) on Xavier

Hi Guys,

We successfully disables spread spectrum on TX1 and TX2 SoMs.
How we can disable it on Xavier platform?

We will check and update.

Please apply below patch to tegra194-a02-bpmp-p2888-a04.dtb

clock@vic {
    allowed-parents = <0xcf 0xe>;
    clk-id = <0xa7>;

[b]+clock@plle {
+    clk-id = <0x64>;
+    pll_freq_table = <0x249f000 0x5f5e100 0x2 0x7d 0x18 0xffffffff 0xffffffff 0xffffffff 0xffffffff>;

init {
    fuse = <0x28 0x0 0x0 0x20000>;

Here is guidance for conversion.
