From ee2e072e8443e48bf8e9059e47fe8890928028bb Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 10 Jan 2014 16:17:28 +0100 Subject: [PATCH] staging: drm/imx: set second plane base address Even though we do not enable the hardware double buffering feature right now, set the second base address pointer (EBA1) as well to increase robustness.
