-- reg : Address range of TMU registers.
-- clocks : TMU's clock source.
-- #thermal-sensor-cells : Should be 0 or 1. See ./thermal.txt for a description.

+description: |
+ i.MX8MM has TMU IP to allow temperature measurement, there are
+ currently two distinct major versions of the IP that is supported
+ by a single driver. The IP versions are named v1 and v2, v1 is
+ for i.MX8MM which has ONLY 1 sensor, v2 is for i.MX8MP which has
+ 2 sensors.
