Driver built into self-built 6.18 (=y): zImage 12.7MB + rv1106-warden.dtb build clean; System.map confirms aicbsp_sdio_driver, aicwf_sdio_driver, rwnx_cfg80211_ops linked with correct bsp->fdrv->btlpm initcall order (host nm/System.map — cross-nm/ar mis-list these, verify with System.map). Recipe captured (driver .c is vendor GPL source in the SDK, not duplicated): - kbuild/ — from-scratch in-tree Kconfig + Makefiles (bsp->fdrv->btlpm link order; tristate->default y; AIC_FW_PATH as a real Kconfig string symbol). - wifi-dt-block.dtsi — sdio_pwrseq (mmc-pwrseq-simple, reset gpio1 PA2) + &sdmmc (mmc@ffaa0000, supports-sdio, cap-sdio-irq, non-removable). - PORT-PROGRESS.md — full file->change log: ~30 timer/netdev renames, 7 cfg80211_ops signature deltas, link_id args, wakeup_source API rewrite, 49 bsp/fdrv symbol collisions renamed aicbsp_priv_*, rwnx_mesh restore. Firmware present on both oem_a+oem_b (/oem/usr/ko/aic8800dc_fw); on-hardware wlan0 verify next.

RV1106 6.18 devicetree
rv1106-warden.dts— our board DT.#includes the vendorrv1106.dtsi(the full SoC: pinctrl, gpio×5, dmac, cru+grf_cru, uart, emmc, i2c, saradc, watchdog, usb, vop, npu, rga, …), then enables only what the wall-HMI needs. No camera/ISP/CSI. Grows one driver batch at a time (see../DRIVER-PARITY.md).rv1106-warden-m2.dts— the earlier standalone minimal DT used to bring up M2/M3 before the full-SoC transplant; kept for reference.
Transplanting the vendor SoC DT onto 6.18 (recipe)
Copy into arch/arm/boot/dts/rockchip/ of the 6.18 tree:
rv1106.dtsi, rv1106-pinctrl.dtsi, rockchip-pinconf.dtsi. Copy the
vendor-only dt-bindings headers into include/dt-bindings/:
soc/rockchip-system-status.h, suspend/rockchip-rv1106.h,
display/media-bus-format.h, and overwrite soc/rockchip,boot-mode.h
with the vendor's (it has extra BOOT_CHARGING/UMS/PANIC/WATCHDOG constants the
DT uses). Then the two hardware deltas:
- Delete the
pscinode fromrv1106.dtsi. RV1106 has no secure monitor in our boot chain, soarm,psci-1.0+method="smc"makes the SMC call fault →Oops - bad mode→Attempted to kill the idle task. (Confirmed on c8a3.) - Enable the peripherals in the board DTS (
&uart2,&emmc, …).
Verified on warden-c8a3: pinctrl, gpio0–4, pl330 DMA, uart1/2/4, i2c3, dw-wdt all probe; full WardenOS userspace boots.
