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.
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).
