Until now, the DT\nbindings were described using a node for the cooling device controller\nand child nodes for all the cooling devices.\n\nRecently, a new set of cooling devices were proposed with the same\nbindings. Those were rejected because DT maintainers do not want this\nformat anymore. In place, a cooling device will be created with an\nid. Whatever its meaning, the thermal OF will bind a thermal zone and\na cooling device by checking the device node pointer + the id are\nmatching the cooling map with the cooling device.\n\nActually this approach is consistent with the thermal which are also\nregistered with a device and an id.\n\nIn order to do a distinction between the old binding with child nodes\nand the incoming new binding, let's rename the registering function\nwith a self-explanatory name.\n\nRename the functions:\n\tdevm_thermal_of_cooling_device_register() -> devm_thermal_of_child_cooling_device_register()\n\nUsed the command:\n\n \t find . -type f -name '*.[ch]' -exec \\\n\t sed -i 's/devm_thermal_of_cooling_device_register/\\\n\t devm_thermal_of_child_cooling_device_register/g' {} \\;\n\nDid not used clang-format-diff because it does not indent correctly\nand checkpatch complained.
