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). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017wB8KB3MMQztRDXCMCkPrf
