[PATCH v4 0/1] Input: cros_ec_keyb: add function key support

From: Fabio Baltieri

Date: Tue Jan 06 2026 - 06:29:57 EST


Hi, v4 of the cros-ec-keyb fn key support, reworked the logic to detect
the fn layer automatically, removed the dedicated dt property.

Changes from v3:
- implemented fn layer runtime detection
- tweaked cros_ec_keyb_fn_code to return back the correct position
code

Changes from v2:
- renamed the dt property to use-fn-map, dropped the example
- added few function comments
- added a helper for obtaining the fn code
- reordered, dt patch first

Changes from v1:
- change struct to short types
- refactored the fn key handling in its own function
- changed props to use the google, prefix
- reworked the properties to use an overlay map rather than a
dedicated one
