CPU

DVFS and thermal zones are not supported, everything else works.

USB

Tegra114 supports XUSB (XHCI), but kernel currently does not support XUSB, so USB can work only in EHCI mode. Moreover, if your device sets up XUSB on bootloader stage, most likely you are not able to use your USB controller in kernel without proper XUSB set up.
