iio: pressure: add Honeywell ABP2 driver

2025-12-21T11:41:13+00:00

Adds driver for digital Honeywell ABP2 series of board mount pressure and temperature sensors. This driver covers 113 different pressure ranges and units on both i2c and SPI buses. The communication protocol involves sending two simple commands to the sensor and there is no register access or a memory map. For this reason the regmap API was not used. The i2c address is hardcoded and depends on the part number. Optional end of conversion interrupt control is present on the i2c variants of the chips. The EOC can also be defined for the SPI variants if a non-ABP2 but compatible chip is to be driven. Tested on two sensors (ABP2MRRT001PDSA3 and ABP2DANT001BA2A3). ocuments/sps-siot-abp2-series-datasheet-32350268-en.pdf Datasheet: https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/basic-abp2-series/d Signed-off-by: Petre Rodan Signed-off-by: Jonathan Cameron

iio: pressure: driver for Honeywell HSC/SSC series

2023-12-11T19:16:35+00:00

Adds driver for digital Honeywell TruStability HSC and SSC series pressure and temperature sensors. Communication is one way. The sensor only requires 4 bytes worth of clock pulses on both i2c and spi in order to push the data out. The i2c address is hardcoded and depends on the part number. There is no additional GPIO control. code is now based on iio/togreg Datasheet: https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/trustability-hsc-series/documents/sps-siot-trustability-hsc-series-high-accuracy-board-mount-pressure-sensors-50099148-a-en-ciid-151133.pdf [HSC] Datasheet: https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/trustability-ssc-series/documents/sps-siot-trustability-ssc-series-standard-accuracy-board-mount-pressure-sensors-50099533-a-en-ciid-151134.pdf [SSC] Signed-off-by: Petre Rodan Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20231207164634.11998-2-petre.rodan@subdimension.ro Signed-off-by: Jonathan Cameron

iio: pressure: Support ROHM BU1390

2023-10-05T13:44:06+00:00

Support for the ROHM BM1390 pressure sensor. The BM1390GLV-Z can measure pressures ranging from 300 hPa to 1300 hPa with configurable measurement averaging and internal FIFO. The sensor does also provide temperature measurements. Sensor does also contain IIR filter implemented in HW. The data-sheet says the IIR filter can be configured to be "weak", "middle" or "strong". Some RMS noise figures are provided in data sheet but no accurate maths for the filter configurations is provided. Hence, the IIR filter configuration is not supported by this driver and the filter is configured to the "middle" setting (at least not for now). The FIFO measurement mode is only measuring the pressure and not the temperature. The driver measures temperature when FIFO is flushed and simply uses the same measured temperature value to all reported temperatures. This should not be a problem when temperature is not changing very rapidly (several degrees C / second) but allows users to get the temperature measurements from sensor without any additional logic. This driver allows the sensor to be used in two muitually exclusive ways, 1. With trigger (data-ready IRQ). In this case the FIFO is not used as we get data ready for each collected sample. Instead, for each data-ready IRQ we read the sample from sensor and push it to the IIO buffer. 2. With hardware FIFO and watermark IRQ. In this case the data-ready is not used but we enable watermark IRQ. At each watermark IRQ we go and read all samples in FIFO and push them to the IIO buffer.
