From 8be7c66995bf06769dc4c5f7a62f3cd62a627e7e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 19 Jul 2012 02:29:52 +0200 Subject: [PATCH] fbdev: sh_mobile_lcdc: Fix overlay registers update during pan operation Updating overlay registers require switching to overlay update mode. This was correctly done when configuring the overlay format and size, but not when updating the base address registers during pan operation. Fix it.
