Hi Angelo,

I think you should add something like that here:
#cooling-cells = <2>;
(the warning is raised when I run 'make dtbs_check')

Julien


I can either add it to a v2 of this series, or you can add it in your patch where
you're actually adding the thermal support.

I have no preferences about who adds it, and I agree that cooling-cells should
eventually get there, so I'll leave the choice to you :-)

Cheers,
Angelo
