Re: [U-Boot] [PATCH 3/3] tegra: Enable LCD on TEC

Hi Thierry,

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.

This has an unrelated patch, but I guess that doesn't matter.
