In reply to Dmitry Osipenko

There are two variants of the NVIDIA Tegra30-based Nexus 7 device:
WiFi-only (named Grouper) and GSM (named Tilapia). This patch adds device-trees for the both variants.

Is it really necessary to list every possible device using a SoC chip? Wouldn't it be enough to just list SoC value nvidia,tegraXYZ and allow any other supplemental "compatibles"?

Yes, otherwise make dtbs_check will give you a warning about the unknown compatible.

I don't know what was the initial intention of having boards defined in a way it's currently done, maybe Rob;Thierry;Stephen;Jon could clarify?
