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.

AI coding assistants helped run these tests and draft this reply; the
results are from the hardware runs.
