+Subject: viafb: correct sync polarity for OLPC DCON
+
+From: Daniel Drake <dsd@laptop.org>
+
+commit a32839696a8eef813a1aff604fbad9a32dff6c95 upstream.
+
+While the OLPC display appears to be able to handle either positive
+or negative sync, the Display Controller only recognises positive sync.
+
+This brings viafb (for XO-1.5) in line with lxfb (for XO-1) and
+fixes a recent regression where the XO-1.5 DCON could no longer be
+frozen. Thanks to Florian Tobias Schandinat for helping identify
+the fix.
+
+Test case: from a vt,
+	echo 1 > /sys/devices/platform/dcon/freeze
+should cause the current screen contents to freeze, rather than garbage being
+displayed.
