            /* disable ssc on PLLE */
            pll_freq_table = <38400000 100000000 2 125 24 (-1) (-1) (-1) (-1)>;
        };
    };

please let me know how to confirm that SSC is disabled after applying this node in dtb !!

Hello,

Is this solution relevant also for 4.2.1 ?
Where can I find TEGRA186_CLK_PLLE ?

The folder “Linux_for_Tegra” does not contain any dtsi files.

Thank you,
Zvika

Hi,
I am also looking for the method to disable SSC for PCIe. My JetPack is also 4.2.1.
Please advise. Thanks in advance.
