Danctnix is the de-facto upstream for PineTab2 Arch Linux ARM images and carries the bes2600 driver in-tree at drivers/staging/bes2600/ in codeberg.org/DanctNIX/linux-pinetab2 (tag v6.19.10-danctnix1). Same 6 commits as the Mobian series (staging-prep-series/), regenerated with paths rooted at drivers/staging/bes2600/ so 'git am' applies cleanly onto a fresh v6.19.10-danctnix1 clone with no path mangling. Per-patch content is byte-identical to the Mobian series; the commit-message bodies are preserved. checkpatch.pl --no-tree --strict passes for all six. UPSTREAM.md extended with a 'Near-term alt: danctnix linux-pinetab2 (codeberg)' section covering the submission route (codeberg fork + PR, or Danct12-direct).
