Needs an SoC specific compatible.
+- reg: physical base address of thermal sensor and length of memory mapped + region. +- offset: reg offset of each sensor.
Should be implied by the compatible.
+- coefficients: An array of integers (one signed cell) containing + coefficients to turn adc value to temperture.
Needs a vendor prefix.
+- hisi,adc-range: adc value range, minimum value is followed by maximum value.
+- #thermal-sensor-cells: Should be 1. See ./thermal.txt for a description.

+Example :
+
+tsensor: tsensor at FFF3000 {
+ compatible = "hisilicon,tsensor";
+ reg = <0x0 0xfff30000 0x0 0x1000>;
+ offset = <0x1c 0x5c 0x9c>;
