Generate pinmux DTSI files from an XLSM spreadsheet by parsing the Tegra pinmux configuration to automatically produce flash-ready pinmux, GPIO default-state, and padvoltage device tree include files for custom Jetson carrier boards.

Configure per-pin SFIO functions, directions, initial states, pull, drive type, and open-drain settings interactively, eliminating manual device tree editing by generating the required BCT DTSI files directly from the authoritative pinmux XLSM spreadsheet.

Generating device tree include files for Jetson Thor requires an active target profile with a custom carrier, a parsed pinmux XLSM, and the Jetson derive-carrier and init-source prerequisites to emit BCT DTSIs into the Linux_for_Tegra overlay tracker.

The generated pinmux DTSI integrates with the Jetson flash process by emitting device tree include files into the overlay tracker with correct carrier-key naming, ensuring they are automatically picked up at flash time via the carrier configuration.

Avoid errors across multiple Jetson carrier designs by automating the generation of padvoltage and GPIO default-state DTSI files from the XLSM spreadsheet, replacing error-prone manual device tree editing and Excel macros with a reproducible process.

This pinmux generation approach works with both Jetson Orin and Thor custom carrier boards, parsing the pinmux XLSM spreadsheet to emit the three required BCT DTSI files into the Linux_for_Tegra overlay tracker for either platform.
