From a2a5729fc1247bb45d794e9d731c0b03bf58096f Mon Sep 17 00:00:00 2001 From: Che-Liang Chiou Date: Thu, 20 Oct 2011 23:04:22 +0000 Subject: api: export LCD device to external apps This patch exports LCD info-query and bitmap-rendering functions to external apps. This patch is tested on a Seaboard. Because the LCD driver is not yet upstreamed, the test was done in a local downstream repo.
