I am trying to disable PCIe spread spectrum clocking in Orin. I followed the instructions found in the How to disable Spread Spectrum Clocking(SSC) on Orin - #3 by kayccc post, but when I recompile using dtc with the patched tegra234-bpmp-3701-0004-3737.dts file with dtc using with the following patch:
tegra234-bpmp-3701-0004-3737-0000.dts.patch (528 Bytes)
which results in the following dts file:
tegra234-bpmp-3701-0004-3737-0000.dts (221.6 KB)
The dtc command is:
dtc -I dts -o tegra234-bpmp-3701-0004-3737-0000.dtb -O dtb tegra234-bpmp-3701-0004-3737-0000.dts
I get the following error from dtc:
Error: tegra234-bpmp-3701-0004-3737-0000.dts:372.14-15 syntax error
It seems that it cannot find definitions for TEGRA234_CLK_PLLE, TEGRA234_CLK_PLLGBE, and TEGRA234_CLK_PLLNVHS.
I decompiled all of the dtb files in all of the subdirectories under Linux_for_tegra/bootloader and I cannot find a definitions for these clock-ids. Where should I look or what are they?
