This patch series adds support for the ENS210/ENS210A/ENS211/ENS212/ENS213A/ENS215 temperature and humidity sensors. Patch 1 adds the required device tree bindings. Patch 2 adds the driver, providing the probe and read functions. Signed-off-by: Joshua Felmeden <jfelmeden@xxxxxxxxxxxxxxxxxxxx> changelog v1 -> v2: sciosense,ens21x.yaml: Add supply to documentation sciosense,ens21x.yaml: Add fallback to compatible strings ens21x.c: Move i2c_device_id next to of_device_id ens21x.c: Use i2c_of_match_device() instead of of_match_device() Many thanks for taking the time to review my patch. Thanks, Josh --- changelog v2 -> v3: sciosense,ens21x.yaml: Update yaml to match dt_binding_check - Link to V1: https://lore.kernel.org/all/20240709-ens21x-v1-2-678521433cdd@xxxxxxxxxxxxxxxxxxxx/ - Link to v2: https://lore.kernel.org/r/20240710-ens21x-v2-0-a37c22018b0c@xxxxxxxxxxxxxxxxxxxx --- Many thanks for the feedback on the driver. Changes in v4: - rename ens21x.c -> ens210.c - rename sciosense,ens21x.yaml -> sciosense,ens210.yaml - General: Changed wildcard ens21x to ens210 to avoid wildcards - Kconfig: added crc7 as a dependency - Kconfig: remove extra blank lines - ens210.c: Moved constants to inline - ens210.c: Created ens210 chip info to handle chip specific conversion - ens210.c: Added documentation for mutex - ens210.c: Fixed sparse complaints from kernel bot - ens210.c: Changed htonl to cpu_to_be32 - ens210.c: Renamed dev_data -> ens210_data - ens210.c: changed of_match to i2c - ens210.c: Added return check for i2c write - ens210.c: Removed switch for conversion check, use chip_info instead - ens210.c: Removed unnecessary retry loop - ens210.c: Convert read to u8[3] type - ens210.c: Ensure 'correct' path is inline, use early returns to break for errors - ens210.c: Changed mutex to scoped_guard - ens210.c: Changed part id mismatch to dev_info from dev_err and removed return - ens210.c: Moved name from id->name to chip_info - ens210.c: Changed data field to be chip_info rather than enum - ens210.c: Formatting fixes (consistent spacing, extra line break at end removed) - Link to v3: https://lore.kernel.org/r/20240710-ens21x-v3-0-4e3fbcf2a7fb@xxxxxxxxxxxxxxxxxxxx --- Joshua Felmeden (2): dt-bindings: iio: humidity: add ENS210 sensor family iio: humidity: Add support for ENS210 .../bindings/iio/humidity/sciosense,ens210.yaml | 55 ++++ drivers/iio/humidity/Kconfig | 11 + drivers/iio/humidity/Makefile | 1 + drivers/iio/humidity/ens210.c | 341 +++++++++++++++++++++ 4 files changed, 408 insertions(+) --- base-commit: 1ebab783647a9e3bf357002d5c4ff060c8474a0a change-id: 20240709-ens21x-8f2530968f2e Best regards, -- Joshua Felmeden <jfelmeden@xxxxxxxxxxxxxxxxxxxx>
