From 00f1099e09d627632b60a3a29cb1bce2339510a7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 27 Sep 2012 15:18:40 +0000 Subject: [PATCH] input: Correct key_matrix fdt decoding Some issues with this were not addressed in the previous series. Fix up the binding decoding to deal with what is actually expected in the fdt. This corrects the broken keyboard on seaboard.
