[v4,0/5] thermal: renesas: Add support fot RZ/G3E

Message

This series adds support for the temperature sensor unit (TSU) found on the
Renesas RZ/G3E SoC.

The series consists of 5 patches (one of which is not related to the thermal
framework) that progressively add TSU support as follows:
- patch 1/5:    adds syscon/regmap support for accessing system controller
                registers, enabling access to TSU calibration values

- patches 2-5/5:  add dt-bindings, actual driver, DT node, and config symbol.

Changes:

v1 -> v2
 * Fix yaml warnings from dt-binding
 * Update IRQ names to reflect TSU expectations

v2 -> v3
 * Remove useless 'renesas,tsu-operating-mode' property

v3 -> v4
 * Improve some commit messages
 * Fix interrupt description in YAML binding file

Regards,
