Thank you Mikko for your comments! Please see my answers inline. - Arto On 05/21/2015 05:40 PM, Mikko Perttunen wrote:
Hi, very good patch! Here are a few small comments. Aside those, you should also add a section to Documentation/devicetree/bindings/gpu/nvidia,tegra20-host1x.txt in a separate patch.
Will do.

The engine has a microcontroller (Falcon) that acts as a frontend for the rest of the unit. In order to properly utilize the engine, the frontend must be booted before pushing any commands.
