BFE EngineeringandClaude Opus 4.8 79ef2df67a kernel: full-SoC DT transplant — batch-1 peripherals at parity on 6.18
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 devicetree

  • rv1106-warden.dts — our board DT. #includes the vendor rv1106.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:

  1. Delete the psci node from rv1106.dtsi. RV1106 has no secure monitor in our boot chain, so arm,psci-1.0 + method="smc" makes the SMC call fault → Oops - bad modeAttempted to kill the idle task. (Confirmed on c8a3.)
  2. Enable the peripherals in the board DTS (&uart2, &emmc, …).

Verified on warden-c8a3: pinctrl, gpio04, pl330 DMA, uart1/2/4, i2c3, dw-wdt all probe; full WardenOS userspace boots.
