RZ/G2L SoC incorporates a thermal sensor unit (TSU) that measures
the temperature inside the LSI.
 
The thermal sensor in this unit measures temperatures in the range from
−40°C to 125°C with an accuracy of ±3°C. The TSU repeats measurement at
20-µs intervals, and automatically updates the results of measurement.

The TSU has no external pins as well as no interrupts.

This patch series aims to add TSU driver support for RZ/G2L SoC.
v2->v3:
 * Added Rb tag from Rob.
 * Updated commit description with technical description of the sensor
 * Included math.h and unit.h for round_up() and MILLIDEGREE_PER_DEGREE
 * Updated the comments.
v1->v2:
 * Removed clk patch and dts pthes from this series
 * Removed devm_add_action_or_reset from probe.
