[PATCH v7 0/2] Input: cros_ec_keyb - add function key support
From: Fabio Baltieri
Date: Wed Feb 11 2026 - 12:34:31 EST
Changes from v6:
- Fixed a bug where normal key were sending the wrong MSC scancode
- Added setkeycode handling so fn functionality is recomputed in
runtime when the keymap is changed
Changes from v5:
- minor renames/cosmetic changes
- dropped the *_key_status array, tracking using the idev->key bitmask
Changes from v4:
- just a comment tweak
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
