Others can feel free to disagree, but IMO ${SUBJECT} patch is not
needed. Instead patch #3 in your series should just define a
"thermal-zones" node at the root level. The "thermal-zones" node is a
well-defined node with a well-defined node name and location (see the
"thermal.txt" binding). If the SoC has a "thermal-zones" node and so
does the PMIC then they'll just be merged.
