Replace every em dash with real punctuation (rewrites, not hyphen swaps)
in docs, code comments, scripts, configs, and the port records; convert
en dashes, curly quotes, ellipsis glyphs, arrows, and section signs to
ASCII; drop machine-writing tell phrases from living docs. ADR titles
now use a colon. The M2 bring-up DTS model string carried an em dash
into the patch series and its record echoes; fixed at both, and the full
series re-verified to apply cleanly onto pristine 6.18.46. One comment
in freshness.h deliberately names the em dash glyph the UI renders as
the unknown mark; that is data, kept as prose naming it.
Verified: cargo tests (sim, config-lint, rs485-bridge), shellcheck,
both driver MC/DC harnesses, patches-apply.
Preparing the repo to go public (ADR-0007):
- CI: kernel-build moves from the self-hosted runner to ubuntu-latest
(installs its own cross toolchain + qemu, caches the pristine tarball).
On a public repo a registered self-hosted runner is reachable from
approved fork-PR workflows — i.e. arbitrary code on private
infrastructure — and the build never actually needed the SDK host.
ADR-0004 marked superseded-in-part; docs/ci-cd.md rewritten (site
specifics now live only in the private deployment log).
- Licensing: LICENSE gains the GPL-2.0 carve-out for patches/ and the
kernel source excerpts (Linux derivatives; per-driver provenance was
already tracked in PROVENANCE.md); patches/README.md states it too.
- Scrubbed from the tip: bench-unit dev credentials and its gadget IP
(m2-boot notes), the site AP SSID+BSSID and a neighboring AP's BSSID
and the device WLAN MAC (wifi bring-up evidence — BSSIDs are
geolocatable), the runner mesh IP. NOTE: these remain in git history;
decision on a pre-publication history rewrite is separate.
- Emoji cleanup across 21 tracked files (kernel port docs, review report,
enforce-mcdc.sh) per repo text conventions: status marks became
[x]/[wip]/[ ]/OK plain text.
- "[maintainer]-gated" process phrasing normalized to "maintainer-gated"
(attributions in dated evidence docs kept).
Verified: zero emojis tracked; scrub grep clean; patches carry no internal
references; ci.yml parses; shellcheck unchanged.

RTC: ported the vendor rockchip,rv1106-rtc driver (rtc-rockchip.c) to 6.18 — one
API delta (rtc_register_device -> devm_rtc_register_device). Verified on
warden-c8a3: /dev/rtc0 registers and reads.
tsadc thermal: ported the rv1106 data + rk_tsadcv9_initialize + the TSADCV9/VOGRF
macros + code table from the vendor; adapted .chn_id[SENSOR_CPU] -> .chn_offset
for 6.18. Verified: thermal_zone0 "soc-thermal" reads 39.8 C.
i2s-tdm: rv1126 fallback compatible added (DAI builds; sound card needs the acodec
port next). saradc still -22 (clk-rv1106 SARADC divider — deferred).
Includes the NPU + RGA open-source port plans (research): rknpu kernel driver is a
small port (RV1106 config already in the vendor driver; 4 dead-code headers need
compat stubs) but no open userspace exists for this NPU gen; RGA = port the vendor
char-dev rga3 driver (WardenOS's librga uses /dev/rga, not V4L2), + a cma pool +
hrtimer_setup. All ports are open source (vendor C source / mainline siblings).
