It would be more typical to order the patches with changes to
tegra124.dtsi first, then changes to board files (that build on the core
SoC support) second.

Can we name that simply "critical"? DT node names are supposed to
represent type of object more than identity of object. Even "critical"
is a bit of an identity, and "trip@0" would be better, but I imagine the
core thermal DT bindings precluded that?
