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. Note to Maintainers: There is a false positive warning reported by checkpatch.pl on patch 1/5 stating that the regmap_config struct should be const, despite the fact it's updated in probe(). 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 Regards, John Madieu (5): soc: renesas: rz-sysc: add syscon/regmap support dt-bindings: thermal: r9a09g047-tsu: Document the TSU unit thermal: renesas: rzg3e: Add thermal driver for the Renesas RZ/G3E SoC arm64: dts: renesas: r9a09g047: Add TSU node arm64: defconfig: Enable the Renesas RZ/G3E thermal driver .../thermal/renesas,r9a09g047-tsu.yaml | 81 ++++ MAINTAINERS | 7 + arch/arm64/boot/dts/renesas/r9a09g047.dtsi | 48 ++ arch/arm64/configs/defconfig | 1 + drivers/soc/renesas/Kconfig | 1 + drivers/soc/renesas/r9a09g047-sys.c | 1 + drivers/soc/renesas/rz-sysc.c | 30 +- drivers/soc/renesas/rz-sysc.h | 2 + drivers/thermal/renesas/Kconfig | 7 + drivers/thermal/renesas/Makefile | 1 + drivers/thermal/renesas/rzg3e_thermal.c | 443 ++++++++++++++++++ 11 files changed, 621 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/thermal/renesas,r9a09g047-tsu.yaml create mode 100644 drivers/thermal/renesas/rzg3e_thermal.c
