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.
