Ported rv1106_codec.c (acodec) + rk_dsm.c (built, dsm disabled — panel uses acodec) into 6.18 (6 ASoC API-delta fixes: gpiod, volsw unify, DAIFMT CBC/CBP rename, remove->void, header swaps). simple-audio-card 'rv1106-acodec'. Fixed the subagent's gap: cpu DAI SND_SOC_ROCKCHIP_I2S_TDM was left =m (module, never loaded on bare _b boot) so the card stuck in 'asoc-simple-card: parse error' deferred probe. Set it + SND_SOC_ROCKCHIP =y. ✅ VERIFIED on c8a3: /proc/asound/cards shows rv1106-acodec; aplay -l shows card 0 device 0 ffae0000.i2s-rv1106-hifi; /dev/snd has pcmC0D0p + pcmC0D0c. Audible speaker test deferred to the bench (with display). Six drivers verified this run: wifi, TRNG, OTP, GMAC, SARADC, audio. audio/PORT-PROGRESS.md; DRIVER-PARITY updated; dts snapshot refreshed.

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.
