* iio: Switch i2c drivers back to use .probe()Uwe Kleine-König2023-05-211-1/+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.

* iio: dac: ad5686: Add support for AD5337Fabio Estevam2022-12-281-0/+2
| | | | | | | | | | | | AD5337 belongs to the same family as the AD5338. The difference is that the AD5337 has 8-bit precision instead of 10-bit. Add support for the AD5337 chip in the driver.

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

* i2c: Make remove callback return voidUwe Kleine-König2022-08-161-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

* iio:dac:ad5686: Move exports into IIO_AD5686 namespaceJonathan Cameron2022-02-181-0/+1
| | | | | | | | | | | | | | | Note these are used in the related ad5696-i2c drivers as well as the more obviously connected ad5686-spi driver. In order to avoid unnecessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the various specific device drivers that use them.

* iio: dac: ad5686: Make ad5686_remove() return voidUwe Kleine-König2021-10-191-1/+3
| | | | | | | | | | | | | Up to now ad5686_remove() returns zero unconditionally. Make it return void instead which makes it easier to see in the callers that there is no error to handle. Also the return value of i2c and spi remove callbacks is ignored anyway.

These devices are pretty similar to AD5671R/AD5675R and AD5694/AD5694R/AD5695R/AD5696/AD5696R, except that they have one channel. Another difference is that they use a write control register(addr 0x04) for setting the power down modes and the internal reference instead of separate registers for each function.
