The only capability of the Armada thermal driver is currently just to read one sensor (the default one) per AP and one per CP. Actually, there is one sensor per core in the AP806 plus one sensor in the thermal IP itself. The CP110 just features one thermal sensor in its own thermal IP. Also, there is no need for the thermal core to poll the temperature of each sensor by software as this IP (at least for AP806 and CP110 compatibles) features an hardware overheat interrupt. This series first improves the readability of this driver, then adds support for multi-channel thermal IPs, and finally adds support for the hardware overheat interrupt. The bindings and the device-trees are updated accordingly. Please note that the thermal IP raises SEI interrupts, from which the support as just been contributed and not merged yet. Applying the last DT patches referring to the 'sei' and 'icu_sei' nodes will require this feature [1] to have been accepted first.
