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.

# The Kernel Patch Series
|
|
|
|
The delta that forward-ports the vendor Rockchip 5.10.160 RV1106 support onto a
|
|
pristine upstream **linux-6.18.46**, as a reviewable, subsystem-split series. Every
|
|
patch applies cleanly onto pristine 6.18.46 (`git apply --check`), and the whole set
|
|
reproduces the 223-file / ~136K-line delta that boots and is hardware-verified on
|
|
`warden-c8a3` (see `../kernel/rv1106-enablement/`).
|
|
|
|
Build it with `../build/build-kernel.sh` (fetch pristine -> apply these -> configure
|
|
with `../build/warden_defconfig` -> `zImage` + `rv1106-warden.dtb`).
|
|
|
|
## The Series
|

|
|
| `15-pinctrl.patch` | `pinctrl-rockchip` RV1106 iomux |
|
|
| `20-arch-dts-bindings.patch` | `arch/arm` DTs (`rv1106.dtsi`, `rv1106-warden.dts`, pinctrl), mach, configs, `include/dt-bindings` |

|
|
| `60-wifi-aic8800.patch` | out-of-tree AIC8800 wifi/BT (the 88.5K-line vendor blob) |
|
|
| `70-audio-codec.patch` | `rv1106_codec` + I2S wiring |
|
|

## License
|
|
|
|
Everything in this directory is a derivative work of the Linux kernel and of

where one is present), the same license the whole repository carries.
|
|
|
|
## Provenance & regeneration
|
|
|
|
Baseline: `linux-6.18.46` from kernel.org (`build/linux-6.18.46.tar.xz.sha256`
|
|
pins the tarball). The series was generated by overlaying the hardware-verified
|
|
source tree onto pristine (build artifacts excluded) and splitting `git diff` by
|
|
subsystem. Licensing/origin of each block is tracked in
|
|
`../kernel/rv1106-enablement/PROVENANCE.md`.
|
|
|
|
Whitespace: `60-wifi-aic8800.patch` carries the vendor blob's trailing-whitespace
|
|
verbatim; `git apply --whitespace=nowarn` (the build wrapper) accepts it. Do not
|
|
re-flow vendor code; it must stay diffable against future vendor drops.
