Tested on an ASUS Zenbook A16 (UX3607OA, BIOS UX3607OA.312), on v7.3 plus out-of-tree Glymur platform/board patches, with the v4 driver (2/4, now db3a9dddab5f in mainline) and a local change that leaves the keyboard backlight to the HID driver: - The EC driver binds from this node at boot. - Both fan speeds and the EC temperatures are readable via hwmon and follow load: under an all-core stress-ng run the fans went to about 5900 and 5100 rpm, and both fans and temperatures came back down within a few minutes after. - 115 s2idle suspend/resume cycles in one boot with the EC bound; its fan and temperature readings kept updating across them. I didn't test the EC's keyboard backlight control, because of that local change. Tested-by: Burke Cates # ASUS Zenbook A16 (UX3607OA) AI coding assistants helped run these tests and draft this reply; the results are from the hardware runs. Thanks, Burke
