Move from the hand-built minimal DT to the vendor rv1106.dtsi (full SoC: pinctrl, gpio×5, dmac, cru+grf_cru, all peripherals), with our lean board DTS (rv1106-warden.dts) enabling only the wall-HMI's needs — no camera/ISP/CSI. Two deltas made it boot on 6.18: overwrite boot-mode.h with the vendor's (extra BOOT_* constants) and DELETE the psci node (no secure monitor → SMC fault → "Attempted to kill the idle task"). Recipe in dts/README.md. Verified on warden-c8a3 (uname 6.18.46, full WardenOS userspace): pinctrl, gpio0-4, pl330 DMA, uart1/2/4 (ttyS1/2/4), i2c3, dw-wdt (watchdog0) all probe. DRIVER-PARITY.md tracks the remaining ports (VOP display, AIC8800 wifi, rknpu, usb2phy, saradc-compat, RGA) toward full parity with the 5.10 kernel.

# RV1106 6.18 driver parity vs the 5.10 vendor kernel
|
||
|
||
Goal: every driver the panel's 5.10 kernel runs must work at ≥ parity on our
|
||
self-built 6.18. Source of truth = the running 5.10 system on warden-c8a3
|
||
(`lsmod` + `/proc/interrupts`, captured 2026-08-24). Verify each on hardware via
|
||
the A/B `_b`-slot loop (`../docs/m2-boot-on-c8a3.md`); ✅ means confirmed on
|
||
c8a3, not just compiled.
