These names are matched with the thermal mitigation device identifiers populated by remote firmware over QMI and define mitigation devices are exposed as cooling devices. Without tmd-names in DT, it is unclear which index corresponds to which binding. With #cooling-cells, tmd-names in DT provides an explicit name-to-index mapping.
