Yours Sob is missing.

The comment looks unnecessary, all of these are HW trip points, right?

Why the alias is needed?

The atlas is a Exynos7 specific codename. The name of node should be a
general class of the device, so maybe:
	atlas_thermal: cluster0-thermal
?

Due to some technical difficulty Alim posted via my account. He will
re-spin this patch via his account soon.

Ok will remove, on this SoC, only THRES_LEVEL_RISE7 support THERM_TRIP, 
rest are used for thermal throttling via a cooling device like cpu-freq.

This is kept to add mutli-instance support of tmu, later ISP and G3D 
will get added.
