Fold bes2600/tx-sdio-dma-oob into the linear series as 7/7.
Re-cover-letter and update testing matrix. Update UPSTREAM.md table
and submission route to list the 7th branch. The PS Mode Error
residual note is removed from the known-limitations section -- it
stopped recurring after 7/7 deployed.
Both staging-prep-series/ (Mobian paths) and staging-prep-series-
danctnix/ (drivers/staging/bes2600/ paths) variants regenerated;
all 14 patch files checkpatch --strict clean (0/0/0).
Net: +117 / -550 lines across 9 files.
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).
