Required properties:
===================
- compatible: Must be "generic-adc-thermal".
+- #thermal-sensor-cells: Should be 1. See ./thermal.txt for a description
+ of this property.
+Optional properties:
+===================
- temperature-lookup-table: Two dimensional array of Integer; lookup table
to map the relation between ADC value and
temperature. When ADC is read, the value is
looked up on the table to get the equivalent
temperature.
+
The first value of the each row of array is the
temperature in milliCelsius and second value of
the each row of array is the ADC read value.
-- #thermal-sensor-cells: Should be 1. See ./thermal.txt for a description
- of this property.
+
+ If not specified, driver assumes the ADC channel
+ gives milliCelsius directly.
Example :
#include <dt-bindings/thermal/thermal.h>
