From 0c5587549b89b8394e341e15833acc4be98ad916 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 23 Nov 2012 00:58:49 +0000 Subject: [PATCH] video: tegra: Update line length to match resolution Instead of storing the computed line length in a local variable, store it in the global lcd_line_length variable to make sure the LCD subsystem can properly draw content for the display resolution. This probably wasn't noticed yet because the only board where LCD support is currently enabled is Seaboard, which runs at a 1366x768 resolution. As it happens this is the maximum resolution supported and also the default that is used to initialize the framebuffer before the configuration from DT is available.
