2023-09-12iio: accel: adxl345: Simplify adxl345_read_raw()Biju Das1-2/+2
Simplify adxl345_read_raw() by adding uscale variable to struct adxl345_chip_info. Also convert variables adxl3{4,7}5_uscale to macros and use it in OF/ACPI/ID match table. Drop enum adxl345_device_type as there is no user.

2023-09-12iio: accel: adxl345: Convert enum->pointer for data in match data tableBiju Das1-5/+15
Convert enum->pointer for data in match data table, so that device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c bus type match support added to it. Add struct adxl345_chip_info and replace enum->adxl345_chip_info in the match table and simplify adxl345_probe().

2023-05-21iio: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
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.

2022-02-26iio: accel: adxl345: Add ACPI HID tableKai-Heng Feng1-0/+7
x86 boards may use ACPI HID "ADS0345" for adxl345 device. Analog replied: "ADS034X is not a valid PNP ID. ADS0345 would be. I'm not aware that this ID is already taken. Feel free to submit a mainline Linux input mailing list patch." So add an ACPI match table for that accordingly. Since ACPI device may not match to any I2C ID, use the name and type directly from ACPI ID table in absence of I2C ID.

2021-07-19iio: accel: adxl345: convert probe to device-managed functionsAlexandru Ardelean1-6/+0
This driver has two parts, one for i2c and one for spi, since the chip can operate with both wire protocols. The core file has a common adxl345_core_remove() function which puts the chip into a powerdown state. This can be implemented with a devm_add_action_or_reset() hook. Doing that means we can register the IIO device with devm_iio_device_register() and get rid of the adxl345_core_remove() function. The dev_set_drvdata() call can be removed as there is no other user of this private data anymore.

2018-08-19iio: adxl345: move null check for i2c id at start of probeAlexandru Ardelean1-1/+4
Fixes ef89f4b96a2 ("iio: adxl345: Add support for the ADXL375"). This was found via static checker. After looking into the code a bit, it's unlikely that there will be a NULL dereference if the `id` object in that specific code path. However, it's safe to add a NULL (paranoid) check just to make sure and remove any uncertainties.

2018-07-15iio: adxl345: Add support for the ADXL375Lars-Peter Clausen1-2/+5
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.
