Until now there was only one thermal zone per SoC but SoCs like Armada A7K and Armada A8K have respectively two and three thermal zones (one per AP and one per CP) and this number is subject to grow in the future. Use dev_name() instead of the "armada_thermal" string to get a meaningful name and be able to identify the thermal zones from userspace.
