Theres possibility that it might not come from that, if nvidia tegra have something like internal voltage ref, and that pinout only used to add a capacitor on it.I believe somebody who reball the SOC itself can test in which soc pin that this caps is connected, and unfortunaltely i dont have access to that.
If i have to take a guess then it should be one of those.
It seems that number 2 is ground.
Anyone have a link for Tegra X1 pinout?
