From 145e97348a3066cf71038d02392aa8063550de6f Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Tue, 13 Mar 2012 21:36:29 -0700 Subject: Input: tegra-kbc - revise device tree support This is an incremental patch updating to the revised bindings for matrix keyboards. This includes an optional "linux,fn-keymap" binding that is not yet implemented, that will be used to specify the Fn-key modifier layout if needed.
