This series adds support for the temperature sensor unit (TSU) found on the Renesas RZ/G3E SoC. The series depends on this syscon patch [1] that has already been queued. Changes: v8: * Use of_parse_phandle_with_fixed_args() for trim values * Update binding doc and collect Rb tag from Rob * Use millidegree computation to for better precision v6 -> v7 * Update DTS trim priperty name and specifier, updading the documentation accordingly * Refactor main driver: remove spinlock usage, using polling timeout as computed from datasheet. Also use polling for get_temp() while using IRQ for trip-point cross detection, and finally add both runtime and sleep PM support. * Add new patch to update sys #address-cells as trim specifier now requires an offset from sys base v5 -> v6 * Minor typo fix * Constify regmap config in patch 1/5 v4 -> v5 * Remove useless curly braces on single line-protected scoped guards v3 -> v4 * Improve commit messages v2 -> v3 * Remove useless 'renesas,tsu-operating-mode' property v1 -> v2 * Fix yaml warnings from dt-binding * Update IRQ names to reflect TSU expectations Regards, [1] https://lore.kernel.org/linux-devicetree/20250818162859.9661-2-john.madieu.xa@xxxxxxxxxxxxxx/ John Madieu (4): 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 | 87 +++ MAINTAINERS | 7 + arch/arm64/boot/dts/renesas/r9a09g047.dtsi | 48 ++ arch/arm64/configs/defconfig | 1 + drivers/thermal/renesas/Kconfig | 7 + drivers/thermal/renesas/Makefile | 1 + drivers/thermal/renesas/rzg3e_thermal.c | 564 ++++++++++++++++++ 7 files changed, 715 insertions(+) create mode 100644 Documentation/devicetree/bindings/thermal/renesas,r9a09g047-tsu.yaml create mode 100644 drivers/thermal/renesas/rzg3e_thermal.c -- 2.25.1
