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.

v1->v2:
 * Removed clk patch and dts pthes from this series
 * Removed devm_add_action_or_reset from probe.
