^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)   A simple common binding for matrix-connected key boards. Currently targeted at
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)   defining the keys in the scope of linux key codes since that is a stable and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)   standardized interface at this time.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)   Some users of this binding might choose to specify secondary keymaps for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)   cases where there is a modifier key such as a Fn key. Proposed names
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)   for said properties are "linux,fn-keymap" or with another descriptive
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)   word for the modifier other from "Fn".
