7 title: Common Key Matrices on Matrix-connected Key Boards
10 - Olof Johansson <olof@lixom.net>
13 A simple common binding for matrix-connected key boards. Currently targeted at
18 cases where there is a modifier key such as a Fn key. Proposed names
19 for said properties are "linux,fn-keymap" or with another descriptive
20 word for the modifier other from "Fn".
