From 41eb2d813f558900884e240c2f723e36c7bd151f Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 6 Oct 2011 15:43:00 -0700 Subject: [PATCH] ARM: OMAP2: Fix H4 matrix keyboard warning Convert to use matrix keyboard to remove the warning "Please update the board to use matrix-keypad driver". Based on similar setup in palmtc.c. Note that this patch is compile tested only because of lack of working hardware.
