* iio: accel: bma400: Add triggered buffer supportJagath Jog J2022-06-111-1/+1
| | | | | | | | | | | Added trigger buffer support to read continuous acceleration and temperature data from device with data ready interrupt which is mapped to INT1 pin.

* iio: accel: bma400: conversion to device-managed functionJagath Jog J2022-06-111-8/+0
| | | | | | | | | | | | | | | | This is a conversion to device-managed by using devm_iio_device_register() inside probe function. Previously the bma400 was not put into power down mode in some error paths in probe where it now is, but that should cause no harm. The dev_set_drvdata() call, bma400_remove() function and hooks in the I2C and SPI driver struct is removed as devm_iio_device_register() function is used to automatically unregister on driver detach.

* iio:accel:bma400: Move exports into IIO_BMA400 namespaceJonathan Cameron2022-02-181-0/+1
| | | | | | | | | | In order to avoid unnecessary pollution of the global symbol namespace move the core bma400 functions into a bma400 specific namespace and import that into the two bus modules.

* iio: accel: bma400: Make bma400_remove() return voidUwe Kleine-König2021-10-191-1/+3
| | | | | | | | | | | | | When an i2c or spi driver's remove function returns a non-zero error code nothing happens apart from emitting a generic error message. Make this error message more device specific and return zero instead in the remove callbacks. As the return value of bma400_remove() is unused then, change the function to not yield a return value.

* iio: accel: Add driver for the BMA400Dan Robertson2019-12-291-0/+61
Add a IIO driver for the Bosch BMA400 3-axes ultra-low power accelerometer. The driver supports reading from the acceleration and temperature registers. The driver also supports reading and configuring the output data rate, oversampling ratio, and scale.
