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@gmail.com> --- changes in v6: sensor driver: - Drop offset for humidity channel. - Use put_unaligned_be16 to assign the 14-bit heater value. - Remove error message if devm_action_or_reset() fails. - Add eror message if devm_iio_device_register() fails. dt-bindings: - remove items before "- const: ti,hdc3020". - add vdd-supply to required. changes in v5: iio ABI: - Document _TROUGH as an info element. sensor driver: - Correct heater enable/disable commands - Rearrang header files in alphabetical order. - Change .info_mask_separate to BIT(IIO_CHAN_INFO_RAW). - Add details to mutex comment. - Add error handling for chan->type in read_raw call. - Remove error message for devm_iio_device_register. 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 | 473 +++++++++++++++++++++ drivers/iio/industrialio-core.c | 1 + include/linux/iio/types.h | 1 + 8 files changed, 563 insertions(+), 1 deletion(-) --- base-commit: 33cc938e65a98f1d29d0a18403dbbee050dcad9a Best regards,
