NVIDIA Tegra SoC pin controller and pin multiplexer
Pin multiplexing and configuration logic for NVIDIA's Tegra system-on-chip family, covering everything from the early Tegra20 and Tegra30 through to current Tegra234 silicon. These chips power NVIDIA's Jetson embedded modules (AGX Xavier, AGX Orin, Orin NX) used in robotics, industrial vision, and automotive prototyping platforms.
recommendation
It should stay because the directory is actively maintained and keeps growing to cover the latest Tegra generations: Tegra234 support landed in 2023, stable backports followed, and substantive commits continue into 2026. NVIDIA still sells Tegra-based Jetson modules for new designs in 2025, so this code is supporting hardware that is shipping today, not just legacy boards.

codex reasoning notes (technical)
Real driver directory: multiple platform drivers and OF match tables for Tegra SoCs. Local tree inspection via shell showed per-SoC drivers up through Tegra234, so this is not legacy-only code. Upstream activity is active: provided static context reports 29 substantive commits in the last 5 years and a most recent substantive touch on 2026-01-19; lore_activity/lore_file_timeline also showed addition of Tegra234 support and later stable fixes. I attempted a removal-discussion subject scan with lore_regex and a lei query; lore_regex timed out and lei could not start in this sandbox, so I found no positive removal evidence and therefore did not escalate. Deployment is still meaningful but niche to embedded/industrial Tegra boards, so 'medium' fits better than 'high'. Source acquisition: first two URLs came from lore_activity/lore_file_timeline; NVIDIA URLs came from web search_query; no source URL was fabricated.
