It could be used to get a temperature using some thermal sensors. Currently, the supported operations are max, min and avg. The virtual sensor could be easily extended to support others operations. Changes in v2: - Fix some warnings / errors reported by kernel test robot - rename some struct and functions with a more accurate name - update the dt bindings: rename type attribute to aggregation-function - factorize a little bit the aggregation functions Changes in v3: - Aggregate thermal zone instead of thermal sensors - Use try_get_module / put_module to prevent thermal providers to be removed - Update the bindings, to be more accurate Changes in v4: - Fix two warnings reported by kernel test robot Alexandre Bailon (2): dt-bindings: Add DT bindings for the DT-based virtual sensor driver thermal: add a virtual sensor to aggregate temperatures Alexandre Bailon (2): dt-bindings: Add DT bindings for the DT-based virtual sensor driver thermal: add a virtual sensor to aggregate temperatures .../thermal/virtual,thermal-sensor.yaml | 86 +++++++ drivers/thermal/Kconfig | 8 + drivers/thermal/Makefile | 1 + drivers/thermal/virtual_thermal_sensor.c | 218 ++++++++++++++++++ include/dt-bindings/thermal/virtual-sensor.h | 15 ++ 5 files changed, 328 insertions(+) create mode 100644 Documentation/devicetree/bindings/thermal/virtual,thermal-sensor.yaml create mode 100644 drivers/thermal/virtual_thermal_sensor.c create mode 100644 include/dt-bindings/thermal/virtual-sensor.h
