The RV1106 VOP is the RV-series "lite" VOP (rockchip,rv1106-vop, VOP_VERSION 2.0xc),
mainline's VOP1 driver. Its sibling rv1126 is already in 6.18, so rv1106_vop reuses
rv1126's register sub-structs + VOP_FEATURE_INTERNAL_RGB + the smaller raster.
Verified on warden-c8a3: with the driver delta + DT (vop enabled with named
"ahb"/"dclk" resets, vop_out repointed to a panel-dpi 720x720 node, pwm-backlight
on pwm1), the VOP BINDS and DRM initialises (/dev/dri/card0), and the PWM backlight
comes up. The register data / version / feature / resets are validated.
Open: /sys/class/drm/card0 has no connector yet — rockchip_rgb_init isn't producing
one ("Cannot find any crtc"). Last mile of M4; needs a debug print in rgb_init + the
panel bus_format, and the pixels must be verified on the physical panel (can't be
checked over serial/ssh). Full recipe + next steps in display/README.md.
Also batch-2 config: GPIO_SYSFS, PWM_ROCKCHIP, crypto (aes/ccm/ctr/arc4), CFG80211,
DRM_ROCKCHIP/ROCKCHIP_VOP all =y; PSCI-style SMC removed via the psci-node deletion.

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.
