iio: Switch i2c drivers back to use .probe() 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: adc: nau7802: convert probe to full device-managed This is a trivial conversion to device-managed functions. The mutex_destroy() calls are redundant, as the data will be free'd anyway.

iio: Remove superfluous of_node assignments If a driver does not assign an of_node to a IIO device to IIO core will automatically assign the of_node of the parent device. This automatic assignment is done in the iio_device_register() function. There is a fair amount of drivers that currently manually assign the of_node of the IIO device. All but 4 of them can make use of the automatic assignment though. The exceptions are: * mxs-lradc-adc: Which uses the of_node of the parent of the parent. * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node assigned to the IIO device before iio_device_register() is called. All other drivers are updated to use automatic assignment. This reduces the amount of boilerplate code involved in setting up the IIO device. The patch has mostly been auto-generated with the following semantic patch // <smpl> @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...) ... -indio_dev->dev.of_node = parent.of_node; @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(parent, ...) ... -indio_dev->dev.of_node = parent->of_node; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

iio: remove explicit IIO device parent assignment This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

iio: adc: nau7802: Expose possible gains in sysfs The Nuvoton NAU7802 ADC is able to adjust its gain but prior knowledge of its possible values was required to adjust it. Users had to guess the possible gain values based on the ADC datasheet or on this driver's code. This exposes the possible values in the in_voltage_scale_available file of each nau7802 ADC device. The gain is set for the whole ADC and is therefore not configurable by channel. Thus, there exists only one in_voltage_scale_available file for each nau7802 ADC device even if it has two separate channels.
