Subject: [PATCH v6 0/5] thermal: renesas: Add support for RZ/G3E

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

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

Patch 1/5 has been duplicated at [1] in USB series. Since it was not reviewed
nor merged yet, I use it here to ease the review, so that which ever is
reviewed first get merged.

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 commit messages

v4 -> v5
 * Remove useless curly braces on single line-protected scoped guards

v5 -> v6
 * Minor typo fix
 * Constify regmap config in patch 1/5

Regards,
