commit 15d203914b44f976d4989fded7369770835a06eb Author: Jimmy Zhang jimmzhang@nvidia.com Date: Fri Nov 14 15:47:12 2014 -0800
google/rush_ryu: devicetree: Add framebuffer resolution settings
When displaying a 800x600 bitmap on 2560x1800 panel, the image is shown very small. So, set the fb to 1280x800 (based on tegra dsi driver default mode setting), a 800x600 image can be shown relatively proportional to panel size.
BRANCH=none BUG=chrome-os-partner:31936 TEST=build and test on ryu
