The saradc -22 was regulator_get_voltage on a dummy vref (no vref-supply in
DT), not the clk divider. Added vcc_1v8 fixed 1.8V regulator + vref-supply
(matching the vendor 86-panel). iio:device0 now reads both channels
(in_voltage0_raw=1023, in_voltage1_raw=246) — the adc-keys path works.
Five drivers verified this run: wifi, TRNG, OTP, GMAC, SARADC.
adc/SARADC-FIX.md; DRIVER-PARITY updated.

GMAC ✅ eth0 Link Up 100Mbps/Full on c8a3: ported rv1106_ops into mainline
dwmac-rk.c (VOGRF RMII mode/speed + integrated FEPHY powerup via CON0;
mainline set_speed/powerup split; bandgap trim omitted — analog opt the PHY
runs without). &gmac enabled; uses the internal ethernet-phy@2. gmac/PORT-DONE.md.
OTP ✅ now reads real data (px30_otp_read): 5211 02fe 084d 5231 ('MR1' chip id),
no timeout. rng-otp/PORT-DONE.md updated.
Batch A + GMAC complete — TRNG, OTP, GMAC all verified on hardware.
DRIVER-PARITY updated.

On-hardware proof (self-built 6.18.46, _b slot): aic8800 modules load,
download firmware, wlan0 up ([device-mac]), iw scan finds real APs
incl. SSID BlueFlare @ -43dBm. RF path fully functional. See
wifi/VERIFIED-on-c8a3.md.
Two changes from the initial built-in attempt:
- Built-in =y DEADLOCKS: aicbsp_init's eager SDIO bring-up (device_initcall,
sequential) blocks the dw_mmc controller probe that would enumerate the
card it waits for (aicsdio.c:597 2s down_timeout -> unregister). Converted
to modules (=m): AIC_WLAN_SUPPORT bool->tristate; loaded late, after the
mmc-pwrseq enumerates the card — the vendor-proven flow.
- Restored fdrv's own md5.o (each .ko needs its own MD5; bsp doesn't export
it). Refreshed kbuild snapshot accordingly.
Kernel-size fix (CONFIG_KERNEL_GZIP -> XZ): the wifi kernel's 12.12MB gzip
zImage overran U-Boot's DTB-at-0xc00000 load boundary (Sysmem Error, FLARE-AB
fell back to _a). XZ -> 8.15MB, ~4MB headroom; also correct for a firmware
kernel. Uncompressed Image ~30MB but the ARM decompressor relocates the FDT
at runtime, so only the U-Boot load-time overlap mattered.
DRIVER-PARITY: wifi ✅ M5; BT 🔨 (module built, HCI not yet exercised).

RTC: ported the vendor rockchip,rv1106-rtc driver (rtc-rockchip.c) to 6.18 — one
API delta (rtc_register_device -> devm_rtc_register_device). Verified on
warden-c8a3: /dev/rtc0 registers and reads.
tsadc thermal: ported the rv1106 data + rk_tsadcv9_initialize + the TSADCV9/VOGRF
macros + code table from the vendor; adapted .chn_id[SENSOR_CPU] -> .chn_offset
for 6.18. Verified: thermal_zone0 "soc-thermal" reads 39.8 C.
i2s-tdm: rv1126 fallback compatible added (DAI builds; sound card needs the acodec
port next). saradc still -22 (clk-rv1106 SARADC divider — deferred).
Includes the NPU + RGA open-source port plans (research): rknpu kernel driver is a
small port (RV1106 config already in the vendor driver; 4 dead-code headers need
compat stubs) but no open userspace exists for this NPU gen; RGA = port the vendor
char-dev rga3 driver (WardenOS's librga uses /dev/rga, not V4L2), + a cma pool +
hrtimer_setup. All ports are open source (vendor C source / mainline siblings).

usb2phy: ported the RV1106 inno-usb2 phy config to 6.18 (rv1106_usb2phy_cfg;
fields map 1:1 except utmi_iddig->utmi_id and chg_mode->opmode; 5.10-only
iddig_output/en/bvalid_grf_sel dropped; phy_tuning left off, guarded so safe).
With PHY_ROCKCHIP_INNO_USB2=y + the u2phy/usbdrd/dwc3 DT enabled, verified on
warden-c8a3: the DWC3 comes up as xhci-hcd @ 0xffb00000 — USB host works. eth0
gadget just needs dr_mode=peripheral.
saradc: added rv1106_saradc_data (2-ch v2, matches the vendor) + the native
compatible. Driver now matches; probe still returns -22 (a clk-rate/setup detail,
not the data) — TODO.
Also captured: the growing board dts (USB nodes), the port fragments under usb/
and adc/. DRIVER-PARITY.md updated: ~14 drivers now at parity on 6.18.

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.
