Capabilities audit — classify every RV1106 SoC block against a 6.18 driver: GMAC (wired eth, enabled on-board), crypto-v3, trngv1 (hw RNG), OTP, mailbox, NPU, audio codec/DSM, pvtm still to port; camera/ISP + SPI are N/A (no HW). Provenance ledger — per [maintainer]'s openness directive extended to already-ported drivers: every ported driver is GPL-2.0 kernel source (vendor-src or mainline-sibling); the only binary in the whole path is on-device wifi-chip firmware, which by construction cannot be host source. No vendor binary is loaded into our kernel. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017wB8KB3MMQztRDXCMCkPrf

RV1106 hardware-capabilities audit — nothing left on the table
Every block in the vendor SoC DT (rv1106.dtsi), classified. Goal: a 6.18 driver
for every capability the hardware actually has, open-source, verified. Camera/ISP
is the only whole class deliberately skipped — the 86-Panel has no camera.
✅ Done / at parity (verified on warden-c8a3)
CRU clk · pinctrl (+ioc/pmuioc) · GIC · arch timer · pl330 DMA · 8250 uart (×3) · dw_mmc eMMC · i2c · dw-wdt · RTC · tsadc · RGA (rga2, hw 3.3.87975) · PWM backlight · USB host (dwc3/xhci) + usb2phy · grf/pmu syscons.
🔨 In flight
- AIC8800 wifi/BT (SDIO on &sdmmc) — the M5 port (subagent building it).
- VOP display — binds; connector is tomorrow's on-panel work.
- i2s-tdm — DAI builds; needs the codec + card (below).
- saradc — driver matches; probe −22 (a clk-rv1106 SARADC divider issue).
⬜ Remaining capabilities to port (open vendor source exists for all)
| Block | vendor compat | 6.18 mainline? | value | plan |
|---|---|---|---|---|
| GMAC (wired ethernet) | dwmac, &gmac okay on-board |
no rv1106 in dwmac-rockchip | HIGH (wired net) | add rv1106 glue to dwmac-rockchip + PHY/DT |
| crypto-v3 (accelerator) | rockchip,crypto-v3 | mainline has only v1 (rk3288) | med | port vendor crypto-v3 driver |
| trngv1 (hardware RNG) | rockchip,trngv1 | none | HIGH (entropy for keys) | port vendor trng → hwrng |
| OTP/nvmem | rockchip,rv1106-otp | no rv1106 in rockchip-otp | med (chip id / MAC) | add rv1106 to rockchip-otp |
| mailbox (HPMCU) | rockchip,rv1106-mailbox | only rk3368 | med (proper coproc mbox vs /dev/mem) | port |
| NPU (rknpu) | rockchip,rknpu | none (no open userspace) | low-med | port kernel driver (npu/PORT-PLAN.md) |
| audio codec + DSM | rv1106-codec, codec-digital | none | med (panel has speaker) | port rv1106_codec.c + rk_dsm.c + card |
| pvtm (PVT monitors) | rv1106-{core,pmu}-pvtm | limited | low (DVFS) | port if DVFS pursued |
❌ Not applicable (no hardware on the 86-Panel)
cif · csi2-dphy · mipi-csi2 · rkisp (all camera/ISP) · SPI (no on-board SPI device).
Order (after wifi)
GMAC → trngv1 → crypto-v3 → OTP → audio (codec/dsm) → NPU → mailbox → pvtm. GMAC + trngv1 first: highest real value (wired net + hardware entropy).
