The thermal IP can probe the temperature all around the processor. It
may feature several channels, each of them wired to one sensor.
+It is possible to setup an overheat interrupt by giving at least one
+critical point to any subnode of the thermal-zone node.
+
Required properties:
- compatible: must be one of:
* marvell,armada-ap806-thermal
- reg: register range associated with the thermal functions.
Optional properties:
+- interrupts: overheat interrupt handle. Should point to line 18 of the
+ SEI irqchip. See interrupt-controller/interrupts.txt
- #thermal-sensor-cells: shall be <1> when thermal-zones subnodes refer
to this IP and represents the channel ID. There is one sensor per
channel. O refers to the thermal IP internal channel, while positive
