2018-07-15iio: adxl345: Add support for the ADXL375Lars-Peter Clausen1-2/+17
The ADXL375 is fully register map compatible to the ADXL345 (including the device ID register returning the same value ...). The only difference is the resolution of the acceleration sensor. The ADXL375 can measure up to +-200g of acceleration.

2018-07-15iio: accel: adxl345: add sampling frequency supportAkinobu Mita1-1/+56
The ADXL345 provides selectable output data rate. This adds the iio channel information for the sampling frequency with that feature.

2018-06-30iio: accel: adxl345: add calibration offset supportAkinobu Mita1-1/+40
The ADXL345 provides the offset adjustment registers for each axis. This adds the iio channel information for the calibraion offsets with that feature.

2018-06-30iio: accel: adxl345: convert address field usage in iio_chan_specAkinobu Mita1-9/+12
Currently the address field in iio_chan_spec is filled with an accel data register address for the corresponding axis. In preparation for adding calibration offset support, this sets the address field to the index of accel data registers instead of the actual register address. This change makes it easier to access both accel registers and calibration offset registers with fewer lines of code as these are located in X-axis, Y-axis, Z-axis order.

2017-08-22iio:accel: drop assign iio_info.driver_module and iio_trigger_ops.ownerJonathan Cameron1-1/+0
The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2017-03-04iio: accel: adxl345: Split driver into core and I2CEva Rachel Retuya1-0/+179
Move I2C-specific code into its own file and rely on regmap to access registers. The core code provides access to x, y, z and scale readings.
