+From 201f57c0a7dfa37bbb47a3f989d35ff00f6a9fe6 Mon Sep 17 00:00:00 2001
+From: Alex David <opdecirkel@gmail.com>
+Date: Sun, 17 May 2015 12:52:54 +0100
+Subject: [PATCH] lenovo/x200: Enable wacom digitizer support for x200t
+
+This patch is based on commit f2b3cd63
+(lenovo/x60: Support digitizer on X60t and X201t)
+
+Tested on Thinkpad X200 Tablet (7450): all pen functionallity
+works (i.e. movements, presure sensitivity and buttons)
+
+THIS IS A REBASE (BACKPORT)
+It's used on an older coreboot revision for this release.
+This patch will be deleted when libreboot next updates
+itself, because the patch is merged now in coreboot upstream.
