iio: pressure: add Honeywell ABP2 driver 2025-12-21T11:41:13+00:00 Petre Rodan petre.rodan@subdimension.ro 2025-12-07T06:00:48+00:00 47d323ce1e8934be36ec475b3bed7ad90d15d35d 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.
