Hello,

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

The series consists of 7 patches (some of which are not related to the thermal
framework) that progressively add TSU support as follows:
- patch 1/7: adds syscon/regmap support for accessing system controller
registers, enabling access to TSU calibration values
- patch 2/7: adds clock and reset signals to the CPG driver

- patch 3/7: adds dt-bindings
- patch 4/7: adds the actual TSU driver for the RZ/G3E
- patch 5/6: adds safety mechanism to make sure we we protect the chip in
case of consecutive read failures
- patch 6-7/7: add DT node and defconfig enablement

Changes:

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

Regards,

John Madieu (7):
