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
