TRNG ✅ VERIFIED on c8a3: rv1106 trngv1 == rk3588 TRNG_V1 IP; one OF-table entry reusing rk3588_soc_data. /dev/hwrng active, rng_current=rockchip-rng, real HW entropy (c697503d... non-zero). Hardware entropy for the panel. OTP 🔨: rockchip-otp0 nvmem device registers; added rv1106_data (6-clock sbpi layout). First reg_read=rk3588_otp_read timed out ('timeout during read setup'); corrected to px30_otp_read (user-mode OTPC_USER interface = the vendor's rk3568_otp_read sequence). Cell reads re-verify next _b boot. See rng-otp/PORT-DONE.md. dts snapshot refreshed (rng+otp enabled).

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.
