iio: potentiometer: mcp4531: Use i2c_get_match_data()

2023-07-29T14:55:48+00:00

Replace device_get_match_data() and i2c_match_id() by i2c_get_match
_data() by making similar I2C and DT-based matching table.

iio: Switch i2c drivers back to use .probe()

2023-05-21T17:54:53+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

iio: potentiometer: Add support for the Renesas X9250 potentiometers

2023-05-20T16:30:33+00:00

The Renesas X9250 integrates four digitally controlled potentiometers.
On each potentiometer, the X9250T has a 100 kOhms total resistance and
the X9250U has a 50 kOhms total resistance.

iio: potentiometer: tpl0102: Convert to i2c's .probe_new()

2022-11-23T20:20:30+00:00

.probe_new() doesn't get the i2c_device_id * parameter, so determine
that explicitly in the probe function.

iio: potentiometer: max5432: Convert to i2c's .probe_new()

2022-11-23T20:20:30+00:00

The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

iio: potentiometer: mcp4131: Fix alignment for DMA safety

2022-06-14T10:53:19+00:00

____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1.  Switch to the updated
IIO_DMA_MINALIGN definition.

Fixes: 22d199a53910 ("iio: potentiometer: add driver for Microchip MCP413X/414X/415X/416X/423X/424X/425X/426X")
