Add support for HDC302x integrated capacitive based relative humidity (RH) and temperature sensor. This driver supports reading values, reading the maximum and minimum of values and controlling the integrated heater of the sensor. Signed-off-by: Li peiyu <579lpy@xxxxxxxxx> --- changes in v4: iio core: - Add an IIO_CHAN_INFO_TROUGH modifier for minimum values. iio ABI: - Document the new _TROUGH modifier. sensor driver: - Add MAINTAINERS. - Use new IIO_CHAN_INFO_TROUGH modifier. - Support the complete heater range. - Remove measurement values from the data structure. - Use guard(mutex)(...), make the code simpler - Removed buffer mode and direct mode conversion code - Minor coding-style fixes. dt-bindings: - removed unnecessary example - add vdd-supply to the example changes in v3: sensor driver: - Removed the custom ABI - Give up calculating values in the driver - Use read_avail callback to get available parameters - Changed the scope of the lock to make the code more concise - Fixed the code format issue dt-bindings: - Use a fallback compatible changes in v2: sensor driver: - Added static modification to global variables - change the methord to read peak value dt-bindings: - change the maintainers to me. - hdc3020,hdc3021,hdc3022 are compatible,I've changed the dirver. - change the node name to humidity-sensor. --- Javier Carrasco (2): iio: core: introduce trough modifier for minimum values iio: ABI: document temperature and humidity peak/trough raw attributes Li peiyu (2): dt-bindings: iio: humidity: Add TI HDC302x support iio: humidity: Add driver for TI HDC302x humidity sensors Documentation/ABI/testing/sysfs-bus-iio | 13 +- .../bindings/iio/humidity/ti,hdc3020.yaml | 55 +++ MAINTAINERS | 8 + drivers/iio/humidity/Kconfig | 12 + drivers/iio/humidity/Makefile | 1 + drivers/iio/humidity/hdc3020.c | 468 +++++++++++++++++++++ drivers/iio/industrialio-core.c | 1 + include/linux/iio/types.h | 1 + 8 files changed, 558 insertions(+), 1 deletion(-) --- base-commit: 33cc938e65a98f1d29d0a18403dbbee050dcad9a Best regards,
