Cherry-picked onto the pinned SDK so the ONLY delta versus the pin is this
patch -- the xHCI controller-death investigation needs a controlled build.
The forward-port omitted the vendor driver's rv1106_usb2phy_tuning with the
note "the phy is functional without it". It is functional, but not reliable:
with these registers at reset defaults the HS link is electrically marginal
under sustained traffic, a bulk transfer eventually stalls, and the r8152
Tx-timeout recovery issues an xHCI Stop Endpoint command the controller never
answers. Measured carrier-on to death over four runs: 14s, 519s, 521s, 584s.

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.
usb2phy: ported the RV1106 inno-usb2 phy config to 6.18 (rv1106_usb2phy_cfg;
fields map 1:1 except utmi_iddig->utmi_id and chg_mode->opmode; 5.10-only
iddig_output/en/bvalid_grf_sel dropped; phy_tuning left off, guarded so safe).
With PHY_ROCKCHIP_INNO_USB2=y + the u2phy/usbdrd/dwc3 DT enabled, verified on
warden-c8a3: the DWC3 comes up as xhci-hcd @ 0xffb00000 — USB host works. eth0
gadget just needs dr_mode=peripheral.
saradc: added rv1106_saradc_data (2-ch v2, matches the vendor) + the native
compatible. Driver now matches; probe still returns -22 (a clk-rate/setup detail,
not the data) — TODO.
Also captured: the growing board dts (USB nodes), the port fragments under usb/
and adc/. DRIVER-PARITY.md updated: ~14 drivers now at parity on 6.18.
