dt-bindings: iio: accel: add ADXL367

2022-02-21T19:33:06Z

The ADXL367 is an ultralow power, 3-axis MEMS accelerometer. The ADXL367 does not alias input signals to achieve ultralow power consumption, it samples the full bandwidth of the sensor at all data rates. Measurement ranges of +-2g, +-4g, and +-8g are available, with a resolution of 0.25mg/LSB on the +-2 g range. In addition to its ultralow power consumption, the ADXL367 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and an internal ADC for synchronous conversion of an additional analog input.

dt-bindings: iio: accel: bma255: Add bosch,bmc156_accel

2021-08-08T15:48:30Z

BMC156 is very smilar to BMC150, but it has only one accelerometer interrupt pin. It would make sense if only INT1 was exposed but someone at Bosch decided to only have an INT2 pin. In this case, it does not make sense if the first interrupt pin is treated as INT1 (since that pin does not exist). Add a note to the bindings that the first interrupt pin is treated as INT2 for BMC156.

dt-bindings: iio: accel: bma255: Add interrupt-names

2021-08-08T15:48:30Z

The binding already allows specifying both interrupt pins, but there is currently no way to describe a board where (for whatever reason) only INT2 is connected. Make it possible to use "interrupt-names" to make it explicit which interrupt pin is meant in the interrupts.

dt-bindings: iio: accel: bma255: Merge bosch,bma180 schema

2021-07-24T14:59:00Z

In Linux the bma180 and bmc150-accel driver cover fairly similar chips from Bosch (just with minor register differences). For the DT schema, this does not make any difference: They both represent I2C/SPI devices, have one or two interrupts plus a vdd/vddio-supply. This means there is no need to duplicate the schema, we can just document the compatibles for both drivers in a single DT schema.

dt-bindings: iio: accel: bma255: Fix interrupt type

2021-07-24T14:57:43Z

Bosch accelerometers similar to BMA255 are initially configured to emit an active-high interrupt signal. This is currently not re-configured in the bmc150-accel driver so the interrupt should most certainly be IRQ_TYPE_EDGE_RISING (or potentially IRQ_TYPE_LEVEL_HIGH). (Unless there is some kind of inverter installed on the board...) At the moment the bmc150-accel driver forcefully requests the IRQ using IRQF_TRIGGER_RISING, which means that the IRQ type is currently ignored in all existing device trees.

dt-bindings: iio: accel: bma180/bma255: Move bma254 to bma255 schema

2021-06-13T16:00:18Z

BMA254 is very similar to BMA253/BMA255 which are both supported by the bmc150-accel driver. In general, there is quite some overlap between the bma180 and bmc150-accel driver, but the bmc150-accel driver has a few more features (e.g. motion trigger/interrupt). Let's move bma254 over to the bma255 schema (bmc150-accel driver).
