[U-Boot] [PATCH 3/3] tegra: Enable LCD on TEC
Thierry Reding
thierry.reding at avionic-design.de
Fri Nov 23 11:58:51 CET 2012
The TEC ships with a 7" LCD panel that provides a resolution of 800x480
pixels. Add a corresponding panel description to the device tree and
enable LCD support in the configuration.
