The instructions your model reads when the skill loads.
Enable, disable, or change the role of USB2 / USB3 SS ports on a
Jetson Thor (Tegra264) or Orin (Tegra234) custom carrier. Captures
per-port wiring (role, max speed, VBUS-EN / OC GPIOs, CC1/CC2 GPIOs
for Type-C, USB3 SS UPHY lane), resolves the SS to USB2 companion
graph from the in-tree DTB, then renders a self-contained kernel-DT
overlay that flips every port action in three places in lockstep
(lane status, port status, host xHCI phys + phy-names).
UPHY lane allocation belongs to jetson-customize-uphy. No ODMDATA
edit. Output is one commit to the composite custom overlay .dts in
the bsp_sources/ hardware repo.
